My contributor application went through in five days and my images have been inspected in under three hours, so StockFresh seem to have got their earlier backlogs under control. So far my acceptance rate has been running at about 70% with the majority of rejections being for soft focus once again. I would suggest that anyone using a D300 or similar camera downsize their images before submitting there. If you do have images rejected then you need to click on the wee red dot next to them to find out the reason - I initially thought they didn't give a reason, but actually it is just well hidden. StockFresh have an upload limit of 50 images per day.
My images have been in Crestock's queue for well over a week now.
ETA - Crestock images inspected after a week and a half, so not too bad after all.
