It might if that were easy.
At least I could manually separate them, or get help writing a script that would.
I don't care what they are named when they get to the gallery end of things, but my current gallery program allows import from a specific directory on your server.
I want my users to upload pics (into different categories/forums) using the threads program so that I can moderate the uploads. Then I can go into the specific category on my gallery program, and import all pics in a certain directory. Then go back to threads and delete the posts.
So a directory would be best... but at the very least a filename prefix I gouess would allow me to move all files named "ForumA*.*" and "ForumB*.*" to separate directories...then import.
