Hi, as a start i would like DATA URI resources from "http://"-loaded images to be enabled. Does such a change posses any security risk? (I see none, but I'm not an expert...)
BTW, why is data uri images loading another data uri images bad?

> I should have been clearer: Mozilla chose to disallow data:uri images from themselves loading other data:uri images for reasons similar to Adam's objection (security complexity). This case is slightly different. I have a followup question though: did you intend to remove the chromium/ResourceHandle.cpp change from the patch?
