Ever wondered how your web site looks like under Epiphany 2.22 running on FreeBSD 7.0? Ok a bit too obscure, how about on FireFox 3.0.3 under the now ubiquitous Ubuntu 8.04 without installing neither of them? Browsershots.org can help.
This free service produces screen shots of any web site URL as it is rendered using a multitude of operating systems and browser combinations, from the common Windows IE7 to the Dillo 0.8 on FreeBSD which only one nerd in a bunker knows about.
