Image Hosting

I hope this is not too off topic, but it kind of has to do with icons =) And if this has been posted, please direct me to the post and I'll delete this entry n_n

Does anyone know a good place to host images? Photobucket told me that I ran out of room, so I deleted some Photo Albums. But, of course, I'm still low on space. So what's a good free place for image hosting? I found quite a bit of sites but I want the best one, so in your opinion what's the greatest image hosting site (besides photobucket =P)
