Ok.. another bug perhaps??
I just uploaded a batch of 50 photos to CanstockPhoto and Crestock.
Stocksubmitter says it uploaded all 50 of the images to both sites.
When I try to submit the images, only 20 images get submitted on Canstock and 13 submitted on Crestock. I waited for a day to see if they were just slow showing up on the site but that doesn't seem to be the case - it appears they weren't uploaded. I went online to look and see if I can see any trace of the missing, unsubmitted images but couldn't find them.
The same 50 images were uploaded and submitted fine on Fotolia and DepositPhotos
