I used to like photobucket, but now it's a piece of **** that automatically jpeg-rapes, compresses, and resizes my images, etc. It's interface went to **** as well with the whole social media bug thing as well. I find myself unable to recommend it anymore. Also, Photobucket has (and always had) a bandwidth cap - if you put something on photobucket that's on some really high-traffic site, you'll get all your pictures blanked until the end of the month once you hit the bandwidth cap, telling you to pay them teh monies.
Coincidentally, I'm also looking for a new image-hosting service. Imgur has been looking like a good prospect so far.
