I went with Flickr (link in my signature) and am happy that I did. It looks slick, is simple to use once you take a few minutes to figure it out, it has a ton of free space, and it displays the images at larger sizes and allows you to zoom in on them more than any other site that I have seen. Flickr also has the option to make individual photos public, shared among only your friends, or private so that only you can see them. The only negative is the square thumbnail images, but they are only square on the album gallery page (i.e., the photo you pick to be the cover of each album) - when you enter an album it displays the full thumbnail.
