Short answer, no.
Long Answer:
I was going to give them a try as they supposedly had an easy upload process. The 'starter kit' told me I had to upload 'at least' 50 images for them to evaluate. I have a standard set of 100 I use for testing new sites, so I cranked that up on their upload site. As soon as the 50th image uploaded, I got an error that I had exceeded my limit and to contact support to upload my limit. When I sent this to my contact she told me that everyone had looked at the images I uploaded and were excited to get more and would increase my limit, and told me how to finish my upload. I followed her instructions but couldn't find my images to complete the upload. I emailed her back. She replied a while later and said that my upload had failed and they didn't have any of my images, so could I try again. I asked how was it they looked at my images if my upload failed, but have got no further useful info other than asking me repeatedly to try again.
