XMLHttpRequest Security errors

Hey /prog/, not a regular but I thought I'd try you guys - I'm running into problems when I try to load cross-board content using xmlhttprequest. Apparently it only works in the same domain, so I get security errors when a link pointing to img wants to load content from dat (the cross-board links send you to a redirecting page which does this). Any ideas on how to work through this? I'm running the code through the Greasemonkey Firefox extension. Thanks!

You can't protect users from themselves. If they are stupid enough to run a mallicious script; so be it. The internet and the standards/protocols it relies on shouldn't be wrapped up in plastic and coated in chocolate for the kiddies to be able to play. It needs to be advanced and improved every day to facilitate human advancement; without giving a shit what some dumbass might do to himself if he tries to use it.
