Photo Hosting Sites Recommendations?

I was wondering what site everyone uses to host photos? I am looking for that one site that is really easy to use, absolutely free, and does not "expire" photos if they have not been "accessed" or seen in a long time. I though I had found a great site to meet those needs with myphotoalbum.com, but I cannot figure out how to post a single photo onto another website. It will allow to post an entire album to another site or to share photos with friends, but I can't get it to post a single photo to another site... Any help with that?

So what sites does everyone else use for posting and sharing your individual photos onto other websites?

Photobucket

and of course

imageshack.us...
ImageShack's mission is to provide an easy-to-use image hosting service.

Cool! Thanks for the quick replies. Photobucket seems just perfect so far...

Any other major ones out there? Or are those the two biggies?

Those two are the most popular, and both have what you're looking for.
