page background images

i guess this is a bug, or maybe it's a mozilla thing, and isn't your problem, but in any case:
when image loading is disabled, background images are still loaded on pages that have them... since these are often one of the more desireable things to NOT have displayed (for accessibility reasons, in some cases), there should be some way to disable them.
