I found this great website http://browsershots.org/.

Everyone that had worked with web pages before will know what a nightmare it is to get cross-browser compatiblity (thanks IE6). Browsershots.org makes screenshots of your webpage in different browsers and then it lets you see the images generated where you will be able to see how your webpage is rendered in different browsers.

It only takes 3 steps:

1) Enter your URL and select which browsers do you want to test your webpage in.

2) Wait until the system finishes executing your request.

3) Check out the result images for the different browsers.
