Themes

Hallo I would like to add an picture in the database "view list"

I add a div Tag in to the "list template" like this: 

<div class="comment">Nice to see you again</div>

and add this lines in to the "CSS template" of database: 

div.comment {
    background: gray;

    font-weight: bolder;

    background-image: url (http://mysite.com/theme/image.php?theme=maxstandard&image=icon&component=page);

}

The parts "background and font-weight work fine. 

But not the "background-image" part.. 

How can I ad pictures to the CSS Template?

Thank you. 

Best Regards

Max
