Photo upload stalls
This has been going on for a while now, back to when the new photo uploader was still being called a beta feature. Sometimes when a photo is being uploaded, it stalls at 100%. It stays there indefinitely (I've let it sit for up to 5 hours), preventing all the other photos in the queue from uploading. This is very annoying when you're trying to upload 100 photos and leave to do something else, only to find it's been stuck at photo #5 (for example) the whole time you were away! The only way to make things proceed is to cancel the photo that has stalled, then re-upload it once the others have finished.
I typically upload larger files in the 2-3MB range. I'm using Firefox (latest version) in Mac OS X. Last time I tried, it did the same thing in Safari.
Please take a look at this issue; having to "babysit" my uploads is one of the worst parts of writing an Instructable because it's such a waste of time!
