Although Flickr is still popular, a lot of people have got very unhappy since it's dropped the ability to have paid accounts, and they are looking elsewhere to park their photographs.
550px (http://500px.com) is a photograph sharing website that displays some really high quality content and users can vote on the images that they see and follow particular photographers. It doesn't have the same community groups element that Flickr has, but if you're a keen photographer, or you want to find excellent pictures, this is worth a look, though I should point out that there may sometimes be artistic nudity.
