Do you have photographs online? You might be interested to know that Kvasir.no, an image searchengine not only displays your images but actually sells them to people for 10 NOK a pop - without sharing the revenue with the people who own the image.
Lets have a look shall we, search on Miklas and the second image is a photo I took of my man in the shoes I made for him a few years back. Search on Dabitch and you'll even find my mother in there. For cat lovers there's my cat, for scooter lovers there's my vespas and for turtle lovers there's my turtle.
Pressefotografforbundet in Denmark have a quote from lawyer August Ringvold who calls it "Plain image theft". Kvasir.no - which is owned by Eniro - defends themselves saying that the images are only shown in 128*128 pixels and that there is no court precedent that forbids this. However, after pissing off thousands of photographers they have removed the "buy this image for your phone"-link, for now.
