I'm done with deleting images for now, as I removed all my best selling images. What I'll be doing next is concentrating on building my portfolio on the sites that pay 50% commission or more. Hopefully there will be a good option to have my own site soon and then there's Stocksy, if they'll have me.
I was annoyed with alamy when they cut commissions to 50% but building a portfolio there that's not on the microstock sites seems like a good way to diversify. Then there's Fine Art America and Zazzle. I'll see if I can get things going with them.
