Browsershots makes screenshots of your website in different browsers

I came across this website called BrowserShots.
It makes screenshots of your website (url to be provided by yourself) from a number of different browsers (more than 50+). On top of it, it is free service and checks your website for browser compatibility for all of the popular browsers and their different versions.

If you need to check your website for browser compatibility in multiple browsers and you do not have resources for testing in multiple browsers, this is the way to go.
Give it a shot!
