Gallery editing

Short, concise description of the idea
How to improve bulk editing

Full description of the idea
Say I have to post a comic book art... some 20 pages, or a graphic novel 128 pages.
If I can add details in the first page and select files to add same to all files... preferably auto changed the page numbers.
And it may help to make all the files named after the gallery by default, with editability by user.

An ordered list of benefits

• Saves lot of time, repeating the same copy pasting and changing.

An ordered list of problems/issues involved
