I run a photography site and I am currently having issues with copyright infringement and I think it's due to my images coming up in google image search results (which is fine and great for SEO) but then people are able to click through to the actual jpg file and download it (e.g. http://website.com/wp-content/uploads/2012/01/image.jpg)
I would like to stop them from being able to access the actual file and instead redirect them through to my homepage. Failing that I would just like to have "Forbidden" come up on screen when they try to access the file.
I'm a very basic level user with WP and HTML/CSS coding so the more layman's terms you can use the better :D
