Nice, i just found out it's possible to look up who has actually bought my pics on fotolia. I never noticed that before 

After some googling these are my biggest buyers: a lot of graphic design firms (webdesign and print), couple of newspapers, some religious groups for some reason and that's about all i could find out.

Did anyone else bother to google their buyers?

Yeah, uploading in smaller batches and if possible at the very beginning of a week is the way to go. And congrats on getting accepted 

It is the total for september, and i've got over 1000 images on shutterstock 

If there's anything that helps getting your downloads up on shutterstock, it would be constant uploading and a lot of time spent. Works for me anyway, shutterstock is my best earner by far 

I can't really judge the photo's since i'm no photographer but i would say the illustrations are pretty good. You just need to constantly upload new designs and maybe have a look around for popular subjects. Maybe try some party vectors, buildings, streetsigns.. ?
