i used to sell on ebay -- until they banned it, i sold digital downloads of images
i've also sold CD collections of my own stock images, but people won't pay more than a few $, so the handling costs just werent worth it
ebay has become a much more hostile place for small sellers in general; i'm down to about 10% of what i was listing a year ago
Sounds like another case of a company starting up to help the small-time individual (or small-time contributor in the microstock world), but big money and corporate greed have now taken over so you have to be a big company (or big contributor) to play the game.
