[Random Talking Bush]

The issue with that is that the page can time out if it takes too long - if you queue a huge number of files, it'll screw it up. My advice would be to have multiple tabs open of the upload page, fill one in and hit upload, and then go to the next tab. This way it won't timeout, and you can fill a second in while the first is uploading.

That's what I do all the time!
