If you want to sell something, it is always better to use pictures to show how good the product is. Everybody knows this fact and, of course, the Portuguese photography store Sitío do Cano Amarelo knows this, too. Therefore the store uses pictures from flickr, which were taken with the cameras the store sells. Actually a good idea, but they give no credits. At least there is the link to the flickr page of the pictures.
At this moment they are selling a Leica R4 with an Elmarit 2.8/35mm. The same setup which I also used. And there they are using my picture "on the floor" which I took some years ago in Blumenau, Brazil.
If you want to buy their Leica, here is the link.
