You can try DM’ing me via Twitter at “sayontan”.

Please provide a URL. The only change in the last update pertained to a control for displaying the number of photos in a Flickr album. If your gallery is not using Flickr albums, your problem is likely not originating from Photonic.

You still have problems with your page markup:

<script><!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-65655300-1"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-65655300-1');
</script></script>

I don’t know if this is something you put in yourself or some plugin did it for you, but the above definition is wrong. In the first line you have <script>, and in the second line you again have <script ...>, and again you have <script> in the third line. This is incorrect markup – <script> cannot have nested <script> declarations. Your markup should be this:

<script><!-- Global site tag (gtag.js) - Google Analytics -->
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-65655300-1');
</script>

… or it should be this:
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-65655300-1"></script>

You have a JavaScript error coming from one of your plugins – the error is showing up from RocketLoader, but I think it is because of one of your other plugins, for which you combined the scripts in RocketLoader.

My question is regarding displaying Unlisted albums. I’ve set up an API key in Smugmug and have configured the Photonic plug-in with the API key and secret, and Smugmug is showing 1 authorised user. However, Photonic Gallery still doesn’t show my Unlisted Smugmug albums.

Did you also perform the step for authentication from Photonic → Authentication? If not, can you complete that step as well?

That looks like a bug in the code. I will release a fix this evening.

On this page your thumbnails are 150px square thumbnails, as per Flickr’s API definition. For sure, you can use a larger size, but the image is not going to be square.

On this page, the underlying images are larger, but Flickr is forcefully setting the displayed size to something like 279px. This results in cropping of sections that you might not want cropped. E.g. look at the album, “Respite Break in France 2019”, where the actual image that Flickr is using is https://live.staticflickr.com/65535/51002320265_ffdb70e29a_z.jpg, but due to the arbitrary trimming of the image, the head of the person is getting cropped in the albums page.

Photonic only pulls the actual, available sizes without modifying the aspect ratio and without applying any crop by itself – 279px is not a standard size published by Flickr; it is just something that they are currently using for their album pages (this changes from time to time). Hence the difference in the layouts.

Can you tell me what shortcode you have in place for this?
