The blue bird travel agency corrected their mistake quickly. They were using a picture from my website and had hot linked it directly from their website. This meant that for every person viewing their site my website had to send the picture over. This resulted in a lot of traffic where in this month the same picture was send over more then 3000 times.
The solution was easy. First copy the image and then put it on your own website. This way it does not bother me and in 99.9% of the cases I would have never found out. The only risk with using someone else his picture is running into a number of laws. In this case I don’t mind they use my picture. After sending them an email they quickly came up with the solution and that’s the end of it.
