One of the biggest problems when designing and developing a new website or rolling out a new look and feel is cross-browser compatibility. Usually the solution has been to have a series of machines, real or virtual, with different versions of the various different browsers out there installed, and then go through each one laboriously.
Fortunately now there is Browsershots which is a web-based browser farm which you can utilise for browser checking. You simply submit an URL to Browsershots and tick the various flavours and versions of browser you want to check against and then wait . . .
Your request is queued and once processed you can view and download screenshots of your site as it look in each of the browsers selected. Because it runs on actual machines these screenshots aren’t kludges, they are the real thing.
