The helper gives me trouble because you have more than 2000 albums, so that is something for me to look into for a future release.
I did discover that at some point over the past few months the “Load More” button ceased working for SmugMug (I know for a fact that it used to work as I have had multiple users use it in the past).
Unfortunately this makes things a bit tricky, but let me see if we can work something out. I would have suggested using the SmugMug API URL for this, but you have too many albums for this to work easily.
Firstly, I dumped out all your albums along with their names and their album IDs here: https://pastebin.com/mg46ysGE. You can paste this out into a spreadsheet – the first column is your album’s thumbnail, the second is the name of the album along with a photo count and the third is the id of the album. You can paste this out into a spreadsheet for easier processing – the content should paste over properly without having to do any manipulation.
The current situation makes it harder to use the Photonic block for Gutenberg, but given your abnormally high number of albums, I would have anyway not recommended using Gutenberg for you – the workflow gets extremely tedious if you have to create multiple galleries. Instead I would suggest using a vanilla shortcode in the shortcode block.
To do this (and to make it all Gutenberg-proof), go to Photonic → Settings → Generic Options → Generic Settings → Custom Shortcode, and put in something like photonic
for that.
Then, in a shortcode block, put in:
[photonic type='smugmug' view='images' album='xyz']
… replacing xyz
with the id for your album as per the PasteBin file I have provided above.
This will display your album. Depending on what type of layout you require I can help you with additional parameters.
The advantage with this approach is that you can pretty much copy-paste this shortcode and replace the album id to show a different album – this is very helpful for cases where you have a large number of albums to navigate.
