Can't list or relist, photo upload issue

[bestchoicebrand]

Not able list (or relist) any item. Notice - "Some of your photos do not comply with our policy", even on existing auctions if I will try to relist item. Every browser shows absolutely same problem.

I'm having the same issue, except I have resized my photos to 500 pixels on the longest side. And it still won't let me upload.

I'm getting frustrated with this 

Any advise?? Please help.
