Redirect direct-link images from Google images to page

Hi, I want to Redirect direct-link images from Google images to page. I have a custom PHP script. All you need to is hotlink the image and when someone directly open the image it redirect the visitor to its URL. What I want to make it so when someone accesses an image via their address bar by typing in: [login to view URL] or other extensions like [login to view URL] It will instead redirect the user to the web page: [login to view URL] [login to view URL]
