[jQuery] How to set background image when file name contains a space?

[[EMAIL PROTECTED]]

Hi, I have an image with path '/documentengine/user/xhuntertest/
Uploaded_Documents/Toad Getting Started Guide1_thumb.jpg'.  When I try
and set this as the background of my DIV using

                $('#frontside').css('backgroundImage','url(' + img
+')');

where "img" contains the offending name, nothing appears.  I figure
this has something to do with the space in the file name as other
images without a space appear just fine.

Grateful for any advice, - Dave
