HOW TO easily verify your website design in different browsers/OSs

Use the free open-source online service - Browsershots. Browsershots makes screenshots of your web design in different browsers.

All you need to do is specify for which of the 40 browsers on Linux, 12 browsers on Windows & 4 browsers on Mac OS you want your screenshots and submit your web address. You can optionally configure settings like screen size, color depth, Javascript/Java/Flash support on the browsers you want to test for. These requests are queued & processed by a number of distributed computers. The estimated time range is specified and you can reload or bookmark the page to view the generated screenshots.

Browsrcamp is yet another useful service that I have tried & liked. It lets you test the compatibility of your design with Mac OS X browsers.

If you just have to test a few pages, these online services obviate the need for purchasing costly hardware.
