Sharing your images has never been easier with the thanks of imgur.  No, this isn’t just a tribute to the fact that all the good names are taken.  Imgur makes image sharing as easy as it can.  You have a browse box, where you can select your picture from, then you continue.  The requirements are it has to be under 2MB, and in the jpg, gif, or png format. 

Have any more questions?  The FAQ would be a good place to start.  Overall I like easy, I like simple so I like imgur for free photo sharing.
