You don't. I sometimes review the rejected images. Its a learning process. Forgetaboutit.
I love this process of art being rejected, I review the reason and look at other stock images and then go to work on my rejected art. In a short exchange, I learn details about the process that will make my work better and more acceptable. Sure I sell my art other places. Each company has different qualifications for presented art or photos. It is up to the seller to meet the buyer's standards. Thanks, Adobe Stock. JH
it is generally not possible to delete rejected images in the file overview.
