img2css

Convert arbitrary images into huge, browser-crashing CSS box-shadow settings.

Example

http://rmer.info/css_mona_lisa.html (your browser will likely not be happy with your decision to visit this link).

You should see two copies of your image, possibly after a lengthy wait. Inspect the second one with Firebug to get a copy of its CSS attribute
Dump the CSS into your stylesheet, under say .mona-lisa, go nuts
