Zuji is doing it, and will pay $0.10 for every picture they “like”, on assumption that one will upload more than one picture. More unique “likes” will earn more money, increasing to $1 to a max of $100 for the top 10 pictures.

Good way to collect content, and a small reward to get content contributors to “park” their existing content in another space other than the established gathering holes like Flickr.

If the model can be refined further (like a quota for example) to target at a broader mass who will probably upload 2-3 pictures instead of the discount hunters who upload millions to cumulatively earn a decent paycheck, it may be worthwhile to see how other brands can also leverage on similar models to encourage some much needed UGC.
