I have downloaded some great images from a specific author whose art is the right look and feel. Unfortunately, I need an image the author does not have, and I would like to contact him or her to commission an image. Is that possible?!
Unfortunately it's not possible to contact the author directly. You will find various images from different contributors that might match what you are looking for.
For more information, kindly get in touch with Adobe support :

I too would find this feature really helpful. I have exactly the same issue. I'd like to contact an author.
