Except that it's not all that useful, since it's only for a single page. I administer Survivor wiki, and when a cast is announced, we have to upload anywhere from 18-24 (depending on season and version) castaway profile pictures (all of which are going onto separate pages), 18-24 thumbnails of those photos (of which are the only set that'll be used on the season page and the season's castaway template), and an additional grayed out version of those thumbnails (which are simply stored until they're used on episode pages to mark an elimination), meaning we have at least anywhere from 54 to 72 images that are going to need to be uploaded at once.

Yes the colored thumbnail pictures can be uploaded at once, but the profile pictures and gray thumbnails cannot, meaning instead of uploading 3-4 times, we'll now have to upload these individually. The MultiUpload is actually much more useful than you think it is, and MassUpload is a much inferior version of it.
