The good news is my Alamy test submissions went through from upload to QC in less then three days. Hurrah!

The bad news is they all failed.

What puzzles me though is that although all four failed, the first one on their table is the only one that has a rejection reason given, that being "Soft or lacking definition", which I am putting down to the upsizing (there are no definite hard edges in the image which doesn't help).
Now I am curious as to whether the other three actually failed ( I understand that on test submissions if one fails, they all fail), or if they didn't bother checking them, as the first one in the table had already failed?
Would they check them all and give a reason for failure for all, or can I assume they did check them all, one failed and the other three passed, but "failed" if you see what I mean because of the "they must all pass QC for your submission to be accepted." guideline .
My main reason for asking this is, I don't know whether I should resubmit the three that were not given a failure reason, plus a new image, or upload four new images alltogether.
Any advice, thoughts and opinions please.
thanks
