Photonic Gallery & Lightbox for Flickr, SmugMug, Google Photos & Others


Photonic takes the WordPress gallery and super-charges it with a lot of added functionality. It adds support for several new sources and parameters to enhance the content and look-and-feel of your galleries. It supports Flickr photos, Albums (Photosets), Galleries and Collections, along with Google Photos photos and albums, SmugMug folders, albums and images, Zenfolio photos, Photosets and Groups, and Instagram photos. You can also set up authentication so that visitors can see private and protected photos from each provider.

When used without the Gutenberg editor Photonic by default overrides the gallery shortcode. In case you happen to be using a theme or plugin that already overrides the gallery shortcode, Photonic provides you with the option to use your own shortcode for Photonic galleries. This lets your plugins coexist. Bear in mind that if you deactivate Photonic you will have to remove all instances of this custom shortcode, something that is not required if you stick to the gallery shortcode.

When used with Gutenberg Photonic creates no shortcodes, rather it creates blocks. If some of your posts were written with Gutenberg and some without, Photonic supports both scenarios.


Photonic has built-in support for commonly used lightbox scripts such as:

Non-GPL alternatives like Fancybox2 and Strip are supported, provided you install the scripts yourself. With the exception of Thickbox the lightboxes have been adapted to become touch and gesture-friendly. See the Lightboxes page for details.

Flickr Support

For demos of Google Photos support visit the Google Photos page. Note that the Google has released the API in a « Developer preview » mode, so there are some restrictions around usage.

SmugMug Support

The following SmugMug concepts are supported in Photonic:

For demos of SmugMug support visit the SmugMug page.

Zenfolio Support

The following Zenfolio concepts are supported in Photonic:

For demos of Zenfolio support visit the Zenfolio page. Note that authenticated content in Zenfolio is not currently supported.

Instagram Support

Instagram photos are supported in Photonic. You can display your own feed, and photos based on tags, and location-based searches. Note that while code has been written to support tags and locations, Instagram hasn’t approved Photonic’s access to others’ photos. This means that currently only displaying one’s own feed will work.

Enhanced Native Galleries

Your existing gallery insertions are left intact. However you can add a style parameter to a native gallery to open it up to Photonic. The style parameter can take any of the values documented on the Layouts page.

500px Support – Historical

Photos and Galleries (a.k.a. Collections, a.k.a. Sets) on are supported in Photonic, but has shut down its API access with effect from 15th June 2018. The code has been left in the plugin in case revives the API, but for now, is not supported.

Video Support

Photonic provides gallery and lightbox support for videos as well. Videos of the following sorts are supported:

  • External videos from YouTube or Vimeo can be opened in any of the lightboxes apart from Image Lightbox or Thickbox
  • Self-hosted or external videos in MP4 formats can be opened in any of the lightboxes apart from Image Lightbox, PrettyPhoto, Strip or Thickbox
  • Videos hosted by external service providers (Flickr, Google etc.) can be opened as a part of a gallery in any of the lightboxes apart from Image Lightbox, PrettyPhoto, Strip or Thickbox. Some lightboxes have issues with specific features. Please refer to the Lightboxes documentation for more.

Deep-Linking and Social Sharing

Photonic provides deep-linking support for non-WP images, and by extension, supports social sharing to Facebook, Twitter, Google+ and Pinterest.

Beautiful Layouts

Photonic displays your galleries either as a grid of square thumbnails (the default), or circular thumbnails (like Jetpack), or random tiles in a justified grid, or a masonry layout, or a random mosaic (a much improved variant of the Jetpack Tiled Gallery layout), or a slideshow. See the Layouts page for details.

Interactive Editing

The WordPress editor shows up with a button that says « Add / Edit Photonic Gallery ». Clicking on it will show you the different types of galleries you can work with.

Gutenberg Support

With effect from version 2.10 Photonic is Gutenberg-capable. There are some steps you might need to take to migrate your existing galleries. Please refer to the documentation.


  • If you are using Gutenberg look for the "Photonic" block
  • If you are not using Gutenberg insert the shortcode for Photonic through the Media Uploader by clicking "Add Media", or click on "Add / Edit Photonic Gallery".
  • Clicking on the Gutenberg block, or on "Add / Edit Photonic Gallery" shows up an interactive flow for you to build out your gallery.
  • The interactive flow shows you the options available and helps construct the gallery easily.
  • If you click on "Add Media" you will see a new tab for "Photonic". This is not available for Gutenberg.
  • Clicking on the "Photonic" tab will show you new tabs, one for each type of gallery. Fill out what you need and click "Insert into post".
  • The gallery placeholder shows up in the "Visual Editor" or in the Gutenberg editor. Each provider's placeholder is designated by its logo.
  • Clicking on the placeholder lets you edit the attributes of the shortcode if Gutenberg is not being used and the interactive workflow is disabled.
  • An example of the "Random Justified Gallery" layout.


This plugin provides 1 block.

Photonic Gallery


You can install the plugin through the WordPress installer under Plugins → Add New by searching for « Photonic », or by uploading the file downloaded from here.

Alternatively you can download the file from here, unzip it and move the unzipped contents to the wp-content/plugins folder of your WordPress installation. You will then be able to activate the plugin.

Once you have activated the plugin, refer to Photonic → Getting Started for a list of capabilities and documentation.


If I disable the plugin what happens to the galleries?

Obviously, your galleries will not show. If you are using Gutenberg you don’t have to worry about anything. If you are not using Gutenberg and you are using the native gallery shortcode, you will not see any empty shortcode tags on your site. But if you are not using Gutenberg and you are using a custom shortcode that shortcode tag will now show up.

When I click on a gallery in the Visual Editor nothing happens. Is the plugin working?

Yes, the plugin is working. Unfortunately the integration of Photonic with the visual editor is complex, and there is a likelihood of conflicts with other TinyMCE-specific plugins. If you come across such a conflict, please report it on the support forum. In the meanwhile you can disable the visual editing capability of Photonic (Photonic → Settings → Generic Options → Generic Settings → Disable shortcode editing in Visual Editor) and you should still be able to edit the gallery shortcode directly through the text editor.

My gallery layout seems to get messed up with random text showing up at various places. Are you sure the plugin is working?

Yes, the plugin is working. The issue you are facing is that you have another plugin (typically some sort of a lightbox plugin) that is modifying the markup generated by Photonic.

Of course, it would be easiest if you were to disable that plugin. If a lightbox is all you need, Photonic’s lightbox can be used to display regular photos as well, from your admin dashboard under Photonic → Settings → Generic Options → Generic Settings → Photonic Lightbox for non-Photonic Images. This will ensure consistency across Photonic and non-Photonic images.

However, if you really wanted to keep that plugin, Photonic offers a way out there too! For each provider (e.g. Flickr, Google Photos etc.) go to the Settings page, e.g. Photonic → Settings → SmugMug → SmugMug Settings → Disable lightbox linking and set that option.

I upgraded, and now my SmugMug galleries won’t show. Are you really sure the plugin is working?

Yes, the plugin is working. Here is what happened: version 1.57 of Photonic moved from API v1.3 of SmugMug to API v2. Your API keys probably were created for v1.3 and need to be authorized for v2. See here for instructions.

Does the plugin support Picasa?

Not with effect from January 2019, when Google terminated the Picasa API. It does support Google Photos though. See the documentation pages for instructions.

Does the plugin support

The plugin has code to support, however has shut down its API access with effect from mid June 2018, so you will not be able to obtain an API key for it, and if you have an API key already, it will have stopped working.

What about other photo-sharing platforms?

Suggestions are welcome for other photo-sharing platforms.

What about other JS libraries?

Currently Colorbox, Fancybox, Fancybox3, Featherlight, Image Lightbox, Lightcase, Lightgallery, PrettyPhoto and Swipebox are supported. Inbuilt support is also present for the non-GPL Fancybox2 and Strip. Both lighter and heavier alternatives are being considered. If you have specific suggestions please feel free to contact the plugin author.

Note that there have been slight modifications to some of the above scripts to make them interact seamlessly with JQuery tooltips.

Are there any known issues?

As explained in the « Description », the Instagram API has been coded to support hashtags and locations, but Instagram itself has not provided Photonic access to those features.

Also, the TinyMCE integration for the plugin is complex, predominantly since Photonic doesn’t rely on a separate shortcode. This can cause potential conflicts with other plugins. If such a situation arises, please report it in the Support Forum, and disable the visual editor capability for the shortcode by specific post-types (Photonic → Settings → Generic Options → Generic Settings → Disable Visual Editing for specific post types). If that doesn’t work, you can go thermonuclear on Photonic’s visual editing (Photonic → Settings → Generic Options → Generic Settings → Disable shortcode editing in Visual Editor) – you will still be able to edit the shortcode using the Text Editor in WordPress.

The « Mosaic » layout may sometimes show 1px wide gaps betweeen images if you set the padding between images to 0. This happens due to rounding errors in the height and width calculations. To avoid this, it is recommended that you use a padding > 0 between images for this layout.

Apart from these, while the plugin can handle pretty much whatever you throw at it, Lubarsky’s Law of Cybernetic Entomology states:

There is always one more bug.

Bug reports are welcome, and handled enthusiastically.

Are translations supported?

Yes, but only for the plugin front-end and the interactive workflow. The admin panel is not translated at this point. Also note that any strings included in the third-party JS scripts are not translated.

Photonic works well - especially with external galleries. It would be nice if a future version would add Imgur support as well directly being able to add image URLs
21 febrièr 2020
Keeping heaps of photos on my own wordpress hosting was not an option for me. This plugin makes it super easy for me to organize my photos into albums (I use google photos) and to display those albums on specific pages of my website. The albums load quickly and the photos scale perfectly to justify across any screen size. There are plenty of settings to make sure everything is displaying as I like. Make sure you check out the instructions pages, they explain how to use the plugin easily.

We were always hitting our storage limit with self hosted galleries, always reducing image sizes & compressing them and even then only able to upload a few. Now switched to Google Photos and this plugin and have a gallery with 10+ years of images in it Very Happy
6 febrièr 2020
Could be intimidating to a beginner level person (obtaining API keys from Google, etc.) but I found setup quick and easy. Created a test page, embedded a Google Album, submitted my new page's URL in Google Search Console and literally 2 minutes later I was able to see an image result in Google Image search from my embedded Google Album. I really didn't expect that to work since the images are hosted on Google's domain. I'll check again later to see if Google has indexed more images from the page. One downside I noticed is that sometimes on page load, the "Justified Grid" has images that are disproportionate until you resize the window and then everything snaps into place properly. (Safari but not Chrome) [EDIT] 12 Hours later. Google Image Search shows 8 photos from my embedded gallery in Google Image Search. I'm very impressed considering none of these images are hosted on my webserver.

I've been using Photonic for some time now, and it has ALWAYS worked so well that I've had no need to ask anything of the Author. When I couldn't figure out how to display a gallery exactly how I wanted recently I posted a question requesting a new layout. Not only was I responded to quickly, Photonic is so flexible that the answer was right there already (under my nose!). I love this plugin SOOOOOOO Much! Now I just need to figure out how to buy Sayonton a coffee or three!
