Possible copywrite infringement?
So....I have this ex-friend that awhile back I had designed an image for with the understanding that it was for personal use only. (He wanted it to make a T-Shirt for himself) and now I found out that he's using it for his business logo.
There was no "contract" persay only emails back and forth about the design.
Do I have any recourse to get him to stop using it for a commercial purpose?
