I was off trying to sign up for photo bucket so I could post a couple of photos from my computer on here but I cant get the sign up to work even though I allowed cookies from the site.
Have you tried www.imagechicken.com? That's what I use to post pictures like the one below ("Make a wish. I feel lucky!") They don't ask for any information at all. If you want to keep track of your upload, though, save the upload link page as a webarchive file.
