I'm wanting to use the art here, but the users who made them for me did not put credits on the images (this was done in signatures on that site). Since the banners aren't credited on the actual image, I don't remember the screen names of the people who made them for me, but I was given written permission to use all of them of course.

Is there any way for me to credit the images so that I can use them here without going against the rules? The images used in all banners are of my horses and were taken by me, but I did not actually make the banners. Since they were given to me with written permission to use them however I wanted online, is it possible for me to credit myself?

I can try to ask some of the girls from that original forum I had the art made on if they know who made the banners, but I am only in contact with a handful of people from there on social media and I'm not sure I'd ever be able to figure out exactly who made what.

We will have to be able to track down any art to the original owner - otherwise we can not approve the art.
