No, I am afraid there is nothing on the site that could possibly prevent illegal copying of peoples uploaded photographs.

Irrespective of what you try to do, there is always someone out there who will go to extreme lengths to get what he/she wants.

People should try and imprint a digital signature (watermarking), within their photographs before placing them on the Internet, as this remains one way of tracing and proving that the original has been "stolen".

Advice on doing this can be found from various sources via the Search Engines.
