Hi,
like you all, I'm still looking for something useful, but there seems to be no better answer for UNIX/Linux than the script I used. Assentially, it opens a VNC server X session 800x600, opens the URL in Mozilla, takes a screen snapshot, and resizes the snapshot to 153x115 px. The X session is finally closed. Lots of sleep statements; snapshot takes two minutes, but you can take thousands over a day.
No guarantee, no support, no nothing. Just as it is. Known issue: It left jobs behind -- no idea why. So clean up later or debug. Insert echo statements to debug.
May be it helps.
