When we attach pictures I assume some sort of tag is associated with each user to meter out storage. If you could build a table that links to those tags then display them by date posted, it would pretty much build a gallery just by compiling those picture links to the original posts. No need to add any new picture copies.
I'm afraid that's nowhere near how it works
Privacy is taken very seriously there, all attachments are encoded so hard that not even with server access we can view them individually outside of SMF interface. They don't keep their names, author, link, extension or any aspect associated with it, they only work with the specific post they've been attached to. I'll attach you a screenshot of the attachments folder on the server just to give you an idea
The only way I could potentially figure something out would be from the date, and I still would not be able to view the file.
The only way to see who posted what is an area in administration, but even then it won't list by member and won't display the attachment without the link to the post. The system is even more complex when you take into consideration that one person may or may not be allowed to view an attachment, a permission that can vary according to the board you're browsing, too. For admins it's not a problem, but for other users it is, because every single item would have to be double checked for permission.
