yep have a look at my profile

here/s the code I used, just put in your own url

Code:


.comment_media {
   background-image:url(http://www.opensourceremixes.com/downloads/the-limitless-potential-cover-art/The%20Limitless%20Potential%20-%20Cover.jpg);
   color:#CCCCCC;
   text-align: left;
   border: 4px solid #000000;
}

or you could remove the background of the comments with:

background: none;

in place of background-image url.. etc
