Working hard at the back-end to this open-source website is 96 Computers, when requested they load your web page and take a screen-shot of the output. Selecting the defaults options on the Browsershots homepage brought back 46 different screen-shot’s of my website, it even includes screen-shot’s of text only browsers in action on my website. The default options took approximately 45 minutes to execute due to a queue, with less selections here you will most probably cut down your wait time.
