That's because it's a link.

Admittedly the border looks odd now. But I wonder how users are supposed to 
guess that if there is no colored border around it. But I digress.

Surely IE draws a border too by default, at least all IE versions I've ever 
seen (from IE 3 to IE 7).

Browsers _generally_ draw a colored border - with the same colors as used 
for texts that are links - around an image that is a link (or inside a 
link). The CSS 2.1 specs don't mention this in their "default style sheets" 
like
http://www.w3.org/TR/CSS21/sample.html
but it's still common practice. You should expect that most graphic browsers 
have (logically speaking) a browser style sheet that includes the rule
:link img, :visited img { border: solid thin; }
or something similar.

If the document does not contain any img elements that should have borders 
(as added in CSS), then you can write simply
img { border: none; }
