iStock is actually my favorite site to upload to in spite of how angry I get with them from time to time. They seem to judge my work on it's technical aspect rather than "oh it's a flower and we don't want it" and my acceptance rate is good there. I'm not one of their best sellers but they at least let me build my port with what I like and give it a chance.
Next to BigStock.... My highest acceptance rate is now with IS !! And even with much that they reject... I am given direction and opportunity to fix it and resubmit. My resubmits have been 100% accepted. I never thought I'd would
EVER say this... but.. I have caught myself thinking about .......exclusive ....with IS.
Go ahead, beat me up... I know I have always bad-mouthed that in the past... but... IS works with me, they take my stuff and... man, they are selling it like no one else is!!
I'm starting to wonder if its the way to go....
