There has been an increase in the number of people stealing images from this website and re-using them uncredited, as if they were their own pictures. A lot of sites have been 'hot-linking' to the images, so the first thing I did was to stop the site from accepting direct links to images.
To try to prevent people from downloading and re-using images, I have been forced to add a copyright notice as a watermark on all the photographs. It is unfortunate that I've been forced to do this. I don't mind people using my photos as long as they ask permission and I get credited as photographer.
I've tried to make the watermark fairly unobtrusive, to avoid it ruining the appearance of the photographs.
