Can I modify multiple data records at once, in this case image data that I messed up while trying to modify a form?
Using Jamroom
suspect your goal is to not allow your members to create different galleries, but to force them to only have one single location to upload all their photos.
If that is the goal, uncheck the "Group By Galleries" checkbox at:
ACP -> MODULES -> PROFILES -> GALLERY IMAGES -> QUOTA CONFIG -> Group by Gallery
That will make the list of galleries that show up on the same page.
I've never thought to turn off the gallery_title, I'll do some testing to see what issues it causes. Suspect it might require an update to the module to account for this setup though.
