Sorry but can’t see my edits so pasting it again.
Hi: Thanks for this, however it still gives me single gallery per line, caches cleared etc. Unfortunately we are in different time zones and out of sync, I have reverted so I can keep going.
The snippet gave me some ideas for direct child css settings but no luck. Used in my child theme footer.php and tested in main theme footer.php. FYI I lose my WP admin bar with this snippet.
*********************
I would like to suggest you add an initial option in the instruction page where you posted this code – for those who don’t understand php, css, etc.
I am using the following until it is updated within the plugin – pretty easy for anyone:
1) create galleries as usual
2) finally create a main gallery with *separate* cover images for each of those galleries (separate meaning not used inside the end gallery – important because these images will have the Caption and Links set in them and mess up the popup if the same image is added into the end gallery. Also in reverse changing it inside the end gallery would lose the Link for the image in the original gallery.)
That sounds complicated but it’s not. This adds an extra page and a couple of extra clicks but minimal. No need to set “Display only first image” in any gallery as the main gallery has only one image per sub-gallery.
I’m fine to wait with this. Pretty simple, a couple of extra steps but working like Albums and Galleries seen elsewhere.
Thanks for your work with this.
