Just noticed that there's an ad on the sale board using pictures I took for a friend to help her sell a horse. The horse sold but apparently the horse is being resold. Do I have the right to ask the seller to take her own pictures rather than use mine? I'm pretty sure my friend who I took the pictures for is not aware of the horse being up for sale again. LOL maybe I should ask for commission as I see the value of the horse has gone up! Maybe I'm just being picky but I guess I'd ask before using someone else's photos. What do you guys think?
