i've used lookpic.com for some pictures, only since i don't upload much. i suppose a drawback may be that there is no account or anything. nor is there a way to see the links to your pics again so you would need to either copy and paste them all to a text file of some sort or take a screen shot and label appropriately.
at the top of the page it says its for torrent sites, but on the bottom it lists several others. they claim no bandwidth limiting or deleting of pics. as far as i can remember all the pics i've uploaded are through that site.
