I just checked my current sales log to see what images I’ve sold through a stock agency. My most recent sale was a photo of ZZ Top… for $6.10, of which I get 60% of the sale. Yup, I made $3.66 from the sale?!? I need to find out the where/when/who/why of the sale, because that is terrible.
My guess is it sold for some little web banner or some other low-paying usage. Even small printed pics in magazines and newspapers at least sell for a hundred bucks or more. Anyway, not all stock image sales are going to bring in big bucks, but three bucks?!? That sucks!
