A good photo hosting site

Ah hai there, fellow vergelings. (zerglings?)

I see lots of pics getting posted up, and I know our dear site doesn't have image upload so..

I was wondering - What's a good site for photo upload and hosting?

It's been a long while since I've thought about having an online photo collection -
last I did that I was still unwilling to pay (now having a little bit more $$ which could go towards that.)

Unfortunately, I'm only aware of
1. Photobucket
2. Flickr

(I'm aware that there've been new options in the past years, but I haven't paid attention to when they came to market!)

any suggestions..? Enlighten me :D

Not entirely sure what I'm looking for, so just fire away..? Thanks.
