Due to a recent post I made on the BOI in regards to photo theft and steps to help prevent it, I've had several ask me privately for the scripting I use to help protect photos on my websites as well as some of my clients. The scripts are attached as text files with this post.
Disable Right Click: This Javascript needs placed in the head tag of the page and will prevent users from right clicking on the page. You can customize the warning message to say whatever you like.
Search Engine Images Redirect: This tiny bit of Javascript will force Google Images to redirect to your domain if a photo is viewed. This will prevent most viewers from having the time to right click and save the image before being directed to your website, which should have Disable Right Click scripted in. This also needs placed in the head tag.
Keep in mind that the internet is ever changing and what works now may not work as browsers and programming evolves.
