but what you describe would only allow you to select up to 20 images at a time (not the 30 or more described in the first post)
Then you change the "20" to "30" or "40" or whatever increment you want:
Choose picture range:
which is not much different from the Bulk Action menu we current provide.
No, this is not the same - I know I've asked about a "Bulk Edit" feature before with no reply given. "Bulk Edit" meaning - presenting a page of say 30 (or 40 or 50 or 60....) pictures and being able to edit the picture name, description and other various fields for each picture, then saving all the changes at once, rather than having to page thru and edit the picture data 1-by-1.
This is EXTREMELY USEFUL - I tend to bulk upload pictures and there's no easy way to edit the picture data except 1-by-1 - ROYAL PITA !
