You could try and find out who they are hosted with and contact the hosts. If it is US based, DMCA notices can work very well, send to their domain registrars also.
Hosts in other countries maybe a bit more difficult.
Search their domain using a whois service and that may give indication of their host.

in less than 10 seconds i had downloaded the 2048 x 1354 version.Thanks guys I might just suck it up then and ensure future uploads are kept to a smaller size. I currently use light rooms sync feature with Flickr which is very handy and great way to organise. It would appear that my cityscape shots that get explored are targeted the most.
On one of these sites someone has posted it as there own work and thanked someone for commenting on it!!!!
This is one example, there are plenty more!
