You don't see any Rangers jerseys with "We Will Win (tonight)" and #11.
Let him put what he wants on his jersey and let him end up on Greg's "Jersey Fouls" becuase that's exactly where he'll be. It'll be entertaining, if nothing else, when this is refreshed with a "told you so" and the fit that will follow.
Well here's how this would work. In a public domain like a hockey game, or just out and about around the town he has the full right to take my picture with that, or anything written on the back of the Jersey. However if he wants to publish it on his website he is going to need my permission and here is why...
I am sure this guy has advertisements on his site in which he makes money from. People come to this site in part to see the pictures therefore I can argue in court that he receives money off my image. I am either entitled to a cut of his profits or he is required to take my picture off the site if he in fact does not want to share the profits.
In any case where a person is making money off of someones image an agreement needs to be signed by both parties in order for them to do so which details the limit of use for that picture even though it was taken with his camera, by him. Don't think for a second I will not take someone to court over the use of my image on thier website. If they are making money off of it I either want a cut of the profits, or it taken off.
