Revenue Model

"Sponsored" Imagery

For example, we'd have a high definition image of a bottle of Coca-Cola, which we'd tag appropriately, mark as Sponsored, release into the Public Domain (or at least CC-BY-SA 3.0 if PD isn't possible), and use as an ad. There are a number of other possibilities for these as well, I think it has a lot of potential. They won't be removed by AdBlock because they're hosted on our site "natively".

Traditional Advertisements

I'd prefer to avoid these if possible, people block them and dislike them.

Selling photography (e.g. stock photos)

We'd have a 20-80(?) split between ourselves and the photographers for any images sold via our site. This could be expanded to include selling prints, etc?

Sell user titles

You'd be surprised how much people pay for a 14px by 14px icon next to their name.

Allow artists to make prints

Exactly what it says on the tin.

Artwork commissions

Ensure safe payment between two users, creator/client. Allow creators to set their price range per-artwork (or set it to "Price is available on request"), allow clients to go to artists with their favorite artstyle and request a commission. We take a small percentage as the "middleman" to ensure safety of transaction between parties, maybe add a rating system for both creators and clients akin to Airbnb or Uber?
