Why hasn't anyone done this yet?
Get a customized tgp script, make it possible to let galleries either expire in a relatively short period (a week or something) or never, add your own galleries and put them on "never expire", let people submit galleries and put those on "expire", make it possible to generate a page with random galleries from the database in a standardized format, make a small script that "rips" the galleries from that page, give that script out to webmasters, who can run it daily to update their tgp.
Voila, you have your own galleries on tons of tgp's every day, and tgp webmasters can get "fresh" listings without having to review tons of galleries.
