I didn't want to totally jack blackmonsters' thread regarding making money from webmaster referrals.
Want to earn some extra money this way? Here's what I do from time to time to earn money from webmaster referrals: at the bottom of my TGP galleries, I include a "Webmasters" link. I space it down a little bit so it doesn't attract the attention of surfers. I know, as a webmaster, I've often ran through galleries on TGPs looking for hot new sites to promote and often click the link to go to the paysite beign promoted to look for a webmaster or affiliates link. Imagine if that link were near the bottom of a gallery? That webmaster could now earn some cash from surfers going to the paysite and earn some beer money from the webmaster link for people who hit that to go to the affiliate program.
Evil Genius Cash pays 10% on webmaster referrals and just by placing a small webmaster or affiliates link at the bottom of your galleries, you can earn a few extra dollars). I know this because I do it myself.
