Photography Bay posts an interesting article on community web sites allowing to share photos for free. Read that article here.
Some limitations of Flickr are also pointed out:
There are some limitations to Fickr’s free accounts that detract from its usefulness. When you have a free Flickr account, you can upload 100MB worth of photos each calendar month. This is a bandwidth limit, and not an amount of space that you have on Flickr servers. Flickr also allows you to create sets for photos from a particular event or just photos that you want grouped together.
