Some images don't appear

I recently changed my blog’s address from /blog/ to the root directory. Everything has pretty much gone dandy except that some of images are not showing up. I’m fairly puzzled by this as some of them are blog entries where the addresses are the same – but some show up and some don’t? Also the white background that is normally on the layout has disappeared – but I know it should work! I figure this is nothing to do with my html, but something else.

I followed the directions of this Codex help (http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory).
