Look at the right side of the site list. It's called Microstock Poll Results. See that Photocase is on the "Low Earner" list with a zero Earnings Rating. That should tell you all you need to know.

I tried a sample of different things from my portfolio but couldn't get anything accepted, so I've written them off (for me anyway)

have had one photo accpeted - I really have no clue what their looking for - and they dont help by telling you anything either.. very strange agency ...

+1, Sites with big attitude, but then they're special right 

Thanks to all for the responses on this query.
By selectively uploading photos I've been reasonably successful getting stuff accepted...so far anyway. We'll see what happens down the road. What attracts me is that they are at least trying to address a particular niche in the market. Perhaps other niche agencies will start to develop and prove to be a better option for buyers and sellers than the massive libraries of general stock. I figure it's worth a try.

Jury still out for me.

17 images accepted (out of about 300 submitted), 7.8 euros of sales in about 3 months. The only things they are accepting from me is really abstract light painting stuff. I've written a review at http://microstockinsider.com/site_reviews/photocase and as I wrote there I'm not submitting my usual stock portfolio.

it's starting to look like a rather time consuming outlet for my 'creative side' - which thinking about it is kind of what I was expecting when I started. nothing ventured nothing gained, and I do very much like the style of images there... my tastes are not exactly mainstream.
