I uploaded AI generative 2 images were rejected due to quality issues and 2 images were accept

Generative AI makes boat loads of mistakes.  It will never replace real artists.  AI isn't smart enough to know what mistakes it makes and correct them.  That's your job.  

It requires talent & skill to turn AI into commercial-ready artwork that Stock customers will buy.  If it was easy, nobody would need Stock sites. 

Closely examine every quadrant of every image and make corrections if you can.  Or remove the image from your submission stack. Compare your best work with other Stock inventory to ensure yours is as good or better than what Stock has.

That should help reduce your rejection rate.  

Good luck.

It seems that each of us finds different AI errors in these, so it's easy to see that Moderators should have quickly rejected them. Keep in mind that they reject based on the first error they see, then they stop looking and move on to the next image. 

1 accept: You see artefacts here:

What is this device?

Whoever approved this did a bad job.

2 quality issues:

This one has been rejected correctly:

It's full of artefacts, but those above are especially prominent.

Even when at a first sight, the food pictures seem to look great, the quality is only good enough to be used in spall printed images and on websites for cheap Chinese restaurants that do their promotion themselves in Word.

The cat pictures are cute, but there are also artefacts to be found with them:

4 accept:

The sheets as a whole are exposing artefacts too. You not only have this very visible outline. 

3 quality issues: See here some issues, there are uncountable ones:

My conclusion is, that the assets that were refused for cause, and that the assets that were accepted got accepted by error.

Hello,

I also think that all of them have some quality issues, and should have been rejected. There are focus issues in the meat photos, and artifacts begin to appear in all of them when enlarged -especially on the edges. This may be a problem.

Actually, none of these should have been accepted.

3 quality issues: Haloing around the cap, a tassel that doesn't connect to anything, pages of the book are rendered poorly, and the hands are poorly drawn

1 accept: Not sure what kind of meat that is but more importantly, I've seen seen a kitchen utensil quite like the one shown

2 quality issues: Again, not sure what kind of meat this is without a title. Buffalo wings maybe? Are those seseme seeds? What are the crumbs?

4 accept: Poorly drawn hands at the very least.
