[Sigia-l] Tool to automate generation of thumbnails of webpages?

[alfred at thunderstick.com]

I have a need to generate many, possibly thousands, of thumbnails of
snapshots of homepages. Is anyone on the list aware of a tool to automate
this when given a URL and some defaults such as height/width? I'm playing
with remote control of a browser and having it do a print screen / copy to
clipboard and automating pasting that into a graphics program and having
it resize, but it seems like there HAS to be a tool that already does this
somewhere :)

The purpose of the thumbnails is for a large-ish bookmarks system that
incorporates the dmoz system - I'd like to illustrate the link with the
thumbnail.

 TIA,
Alfred Werner
