Add a LIKE button to my website

Hi there, The request is: We have a website running which uses a lot of Galleries with Photo's. Now we like to add a clean and sophisticated LIKE BUTTON to each Photo. Note: same idea as Facebook Like Button, but surely my Like Button should run independant from FB. A good example of what we envision is the LIKE BUTTON used on the Blog site of SquareSpace:, pls check: [login to view URL] See also the attachment. It s nice, clean and cool. And it works.
