I have had a pretty severe drop in sales on Dreamstime. As a matter of fact, my numbers are down across the board except for StockXpert and Fotolia. Anyone else seen similar issues?

Thanks in advance.

I have been making more than ever on Dreamstime, but I consistanlty submit there. I try and submit at least 15 images a week to each of the agencies and I have rarely seen a drop month to month. January was a tight time, but I still managed to barely beat December.

Submit more images?
