For example, me and another byc member have been talking back and forth about the status of some shipped eggs sent to me, threw PM'ing. Then the other day we got talking about a different breed of chickens so I tried to attach my Cochins picture but it gave me an error message. So I started a new PM with her and boom I was able to attach the same picture with no problems what so ever.
I tried copy and paste won't allow me I hit the attach picture button, gives me temporary out of service try again later. But if I compose a new PM works just fine.
