One day I needed to create thumbnails of about 300 websites, this
would usually take a very long time, so I wacked together a simple
shell script which makes use of Firefox, Xvfb, and ImagemagickThe
script creates a virtual X desktop, starts a Firefox instance, and
then, using the openUrl command, proceeds to load each website and
capture a screenshot one at a time.If you cannot get Xvfb

spare linux desktop. I suggest you play with image magicks cropping
tools to remove the firefox decal. here is the original bash script
