Userpics In Mid-Century Template

I use Mid-Century and MTOS 4.21 (I know they have 4.23, but I don’t have FTP access). I’d like to at userpic functionality (which I did) from [http://www.movabletype.org/documentation/designer/publishing-comments-with-userpics.html]. But when I do a test comment, the comment’s userpic is at the very side of the comment, making it look ugly. How do I add a border and move the userpic to the right-hand side of the comments (like http://mt4.juneeonline.com/babble-on/archives/2008/06/add-a-menu-bar-to-mt-themes.php#comment-163)?

Oh, and to other Mid-Century users, it’s better to put the userpic code in Individual Comments, so the userpic doesn’t show up above the comments.
