When you open the URL in Safari with TOT WebKit and hit Command-. before it's finished loading but after images have started loading(*), all partially-loaded images change to the error image. This is a (recent) regression from shipping WebKit. * - You need to be quick or have a slow connection or find a page served from a slower server.
Regressed in <http://trac.webkit.org/projects/webkit/changeset/20178>.
I was wrong, this is not a regression from Safari 2.0! I had forgotten it because TOT behaved differently for so long.
Regression or not, Hyatt reccomended an easy fix I'm putting a patch together for right now
