A fellow used an image of mine without permission to advertise an event. The image had nothing to do with the event.
I had to laugh. You see, a few years earlier he threatened to sue me for using an image that wasn't even his, on the letterhead of a letter I wrote to him (in his capacity as club secretary). I knew he was on a power trip so I just told him to contact my lawyers.
He has no idea the image he used is mine. Now, that is a laugh.
If you're not a professional photographer and someone uses your photo, be proud someone thought your photo was worth using.
If you use someone else's photo, a by line would be nice.
If you don't want your photo's used, put a "copyright" on them as a watermark.
