I have a shutterstock rejection question...
I uploaded 3 files of fruits 1. A lime ---batch one
                                         2. A kiwi ---batch two
                                         3. A kiwi and a lime ---batch two

They was uploaded in two different batch. One was only the lime and the other was the kiwi and the kiwi and the lime.

In the second batch, my kiwi picture was rejected for:
"similar submissions - to many of the same subject"

I have one file in my portfolio who is about food before this review...
My question is:- What they are meaning whit this rejection?
                             
-To not upload similar subject in the same batch?
If it's that...I just don't understand!

Question 2: Can I resubmit this file and how?

yeah that is puzzling.  Perhaps they meant that they allready had too many of that type of image in their database - or else they selected the wrong button?... not sure.
