Flickr seems to be the picture hosting website of choice these days, but its always seemed a little awkward to me. Plus, you can only have 3 albums, which annoyed me to no end! So, I've switched:

I'm a huge google fan, and here you can have as many albums as you want, and its really easy to use. There is a 250mb limit, but if you really think people are interested in seeing that many pictures of you, then maybe you deserve to pay $25 a year.
