What is the easiest way to convert a webpage into a jpg
or png file?  I've seen several programs that can do
various conversions, but nothing open source that can
do it in a single conversion.

Just wondering if anyone on the list has suggestions
for something I can put into a script to convert a
webpage into a file I can use with my screensaver.
