Redirect "not found" images to an alternate image

Hi!

I run an image hosting service and I delete images from time to time, to save disk space and bandwidth. I would like to redirect the "not found" images to a local, static image. Can anyone help me do this?

Thanks,
S.

 

You can use some mod_rewrite tricks to decide which type of 404 to serve based on file extension. Google brings up a sitepoint thread that explains it: http://www.sitepoint.com/forums/showthread.php?threadid=112412
