Hello There Almighty Coppermine Developers.
I've been using the Batch Add functionality, and it seems to be working well. I'm noticing a small issue with the check boxes. When I select a folder to add that has sub-folders in it with pictures, I get multiple "Check/Uncheck All" buttons on the page. for each sub-folder there's a "Check/Uncheck All" box. If I uncheck some boxes in other folders and if i accedently check that "Check/Uncheck All" box it will go through the whole list (even other subfolders) that are listed on that page and Check or Uncheck all of them again, and I have to start all over again....
It's not a show stopper, just a little annoying i guess.
Doesn't happen if you preserve a clear structure: folders that contain sub-folders should not contain files as well. Only the last "branch" in the folder tree should actually contain files.
