What is a good site to upload photos to that everyone can see?

Flickr if you want to share entire collections. Or you can use TinyPic for posting pics to blogs, forums, and message boards online.

I second Flickr

http://23hq.com is the best, if only because it doesn’t contain hidden limits. I was an avid and very satisfied user of Flickr until I reached my 200th photo and it said it wouldn’t display any more photos unless I upgraded to a pro account. 23 has most of the features, doesn’t suck as much as Zooomr, doesn’t have the nasty limits of Flickr and they have a very friendly team that will quickly respond to your queries.

Also, if you went on, say, a holiday, and several people made pictures, it’s very easy to each have an account there and upload your own pictures separately, then create a photogroup to have them in one place.

Oh delightful irony.

EDIT: Of course even greater irony that I uploaded that image to imageshack :P

I really like Flickr.
