add more button

Where do I add the snippet of code from the documentation?

You are not supposed to add “the snippet of code”. The code is just showing you that if you have the more attribute as a parameter of your shortcode, you will see a button if you get more than 100 photos.

When I add it in ‘generic settings’ ‘custom shortcode’ all my albums disappear from the site.

You should not be putting it there – that option is only if you want a custom shortcode tag instead of gallery.

How are you creating your galleries? If you are using the gallery wizard, there is an option there to set the ‘“More” button text‘ in the last screen of the wizard. If you use that, it will add the button to your gallery.

Hey
Then I’m doing it all wrong.
I don’t get a ‘more’ button. Just 100 pictures.

We upload our pictures directly in google photos.

How are you creating your galleries using Photonic?

We use the shared google albums. Every photo is dropped in shared albums and those albums are placed in a mason grid. Is that enough info or do you mean something else? (Great plugin by the way) Just noticed now that big albums aren’t displayed beyond picture 100

No, I mean how are you adding your galleries to your posts? What button are you clicking to do so?

We have just one big gallery. We don’t individually add them to posts.
When people open an album, they see the first 100 pictures from that album. But they don’t get a ‘more’ button to see the other pictures.
This is the photo page : https://bulokk.be/fotoalbum/

I am not asking that. I am asking how you added your gallery to this page. What button did you click for Photonic? Are you using the WordPress Classic Editor or Gutenberg? Or did you simply type the shortcode into your post?
