We have an ongoing problem with people breaching our copyright by stealing our photographs and using them on their web sites. Where we can we tackle this via legal action (and indeed this very week we've succeeded in getting substantial compensation for the theft of one of our photographs).
We've also recently had another site taken down completely after the stole one of our photographs.
However in some cases other web sites are simply embedding our photographs in their pages, so the photograph is actually served from our own web server which adds insult to injury as it also means they're stealing our bandwidth. To tackle this we've now tweaked our server so, if someone does this, then instead of the photograph their visitors should see this:
However if you see that image on a page on our site then we have a problem, so please let us know.
