I haven't had time yet to think this through or experiment with it, but I will once I get time unless someone else has already done this or tried it. Anyway I was thinking that since we can block people hotlinking images through htaccess and send them a specific image (URL), why not send them an iframe with custom contents in it? Basically instead of sending them to a custom image, send them to a html file with an iframe that displays whatever you would like.
Won't work. You can't redirect an image to an html file. (I've tried). If you do figure it out though, I'd love to use this. I was wanting to use my site logo with an active link back to my site. I'd get thousands of backlinks this way :evilgrin:
