I would give DT still a chance. 50 images are to small amount to decide wich agency to keep.

Good luck.

Being also a newcomer I would not rush into general conclusions on trends in a market of millions of pictures and photographers.

My initial strategy now, is to upload a hundred or two images to each agency and see what sells. I had 8 sells in my first 2 months on DT, which I consider not that bad with only 100 submissions.

Don't give up and best of luck to us 

I guess with 50 files up a sale a week is pretty good for fotolia. Even I've had issues with DT but i guess it's about giving them images they can sell

Hi
DT is good for exclusive contributors because you get higher commissions an visibility and get paid 20 cents per accepted image

Also DT has the best acceptance rate of all bigger sites.
they pay quickly but you have to reach 100 usd.

Anyway to get some money, and this is true for all sites, you need to upload some hundreds of pictures not few of them

To begin, I suggest to go exclusive in DT or  FOTOLIA or Istock
depending on your picture quality and editorial content you have.

because DT accepts editorials, FOTOLIA not
Istock accepts editorials but it's very severe on them about description and caption.
and they consider editorials all the pictures that may have the minimal copyright issue, so you can get many rejections about this.

Istock doesn't show you the real earning up to the end of following month but its probably the one where you can gain more money.
Istock have the best acceptance rate for non-editorial pictures
and they pay higher commissions to exclusives contributors.
