Actually, at one time we did support bulk uploads, that was what cathy was referring to. If you look at the bottom of theupload screen, you will see something that says skip the upload and process the pictutes in your upload directory.
The trick is to use FTP to upload your pictures into that directory. But that meant the staff had to assign a FTP user id and password to each person who wanted to do that. and that was adifferent id password than the rest of the site. Then the person would have to set up a ftp client and that would need significant support from the staff and many of the staff have np idea how to do that. either. So I stopped making that a generally available option.
I suppose if a person already new how to run a FTP client,etc, I would probably set it up for them.
