Okay, so lets say a website allows users to upload html code, b ut only from webistes they allow. Im guessing tshis is done my scanning img src's for urls that website will only sllow etc. Is there a way to cancel out this scanning of code, so that the user could upload images from a site that isnt allowed? Perhaps some way of implementing the poison null byte?

i tried: <IMG SRC=¨http://imagelocation.com/file.jpg%00¨>

but that didnt work. anyone have any suggestions?
