I'm used to store my nice shots on my Flickr account, but I'm making an effort to start putting the ones that can be used by an encyclopedia here.
My prefered media license is the Creative Commons by-sa and the majority of my hobby work on Flickr is under it. The ones that aren't is just because I don't have permission to do so or wanted to avoid them from being used somewhere else for some reason (i.e., uploaded under fair use, not taken by me, etc).

Yet this page is horrible, I'm an expert in web design and nowadays I work on a top secret project (to be released under a free software license asap) :)
