I've been doing Stock for a while, but have recently been thinking about removing all my photos from all the websites - I truly believe something better will come along on the blockchains of the future: I've seen first proposals for stock sites on the blockchain pop-up and am waiting for 'the one' :-) They will have different business models and from what I see we will be able to keep around 80% instead of 0 (and believe 100% must be possible as well, like you get 100% of your content's worth on Steemit as well).
Have you considered this road yet too?
And yes, it's always the funny pics you don't expect to make a dime that will make you most! :D
If I can get 100% of the sale then that would be great. But the problem is also where the buyers are. A great system of stock photography on a block chain where photographers make more per sale sounds like a fantastic idea, but if you don't actually make any sales then there is no point.
Until something better comes along I still think Getty is the best place for my photos to make lots of small amounts, rather than zero larger amounts.
