I'm just curious whether this is possible for possible future reference, it seems simple and I think it can be done with a line in htaccess but I'm no programmer. scenario - 3 sites: Site A hosts a 1mb image. Site B hotlinks the image. Site A wants to allow the hotlinking but use Site C's bandwidth. Can Site A upload the image to Site C and use htaccess to route all requests to it from Site B to Site C thus Site A using no bandwidth for this image?
Not really ... the other site would have to store the image on their sever, and then just link to it there instead of from yours.
