swimswimswim: I was having the same problem too. Go into your plugins folder and widgets directory to the widgets.php file and do a search for wordpress.com and you’ll find it. You’ll see it right under the RSS meta data links.
That’s exactly right, thanks! I’ve got it in the css for my site (not in my blog section of css) so I’ll see what it does to other images. Looks like I need to read up on float.
