Show random thumbnail?

edited September 2006 in Vanilla 1.0 Help
In Gallery 2, one can do a php read() on /gallery/main.php?g2_view=imageblock.External&g2_blocks=randomImage, and get a block that displays a random thumbnail, linked to the full sized version of that image.

Anyone got a way to do that easily, or at least just grab a random thumbnail and figure out what it actually links to?
