[quote=Leslie B]I emptied the cache in Safari, closed the browser, reopened it and called this page back up. There are still the little blue question-mark boxes in place of people's avatars, as if the page is trying to load a picture but can't find it. They remain even after the page is reloaded.[/quote]

This is ummm "normal". Safari is rendering the page a little differently than IE or FF. This is the kind of stuff that drives web developers nutts.
