Here’s a techie question for all of you: if you’re viewing this in Firefox, you probably see a picture of a Canada goose in the upper-left corner of this entry. If you’re viewing it in MS Internet Explorer, however, you might not see the picture – only a blank space. Can anyone tell me why this happens, and how to fix it?

Well, I’m not the one to answer that for you, but for what it’s worth, I can see it fine in both firefox and IE7.
I see it in IE7
