Sub domain image referencing

Hello again, DOCUMENT_ROOT is...... /htdocs/www I have a php file ( showdatabases.php) in my subdomain area /htdocs/util/ it loads up just fine: and if you click it, you will see my database structure if you like..:) www.util.consumergrapevine.org/showdatabases.php I have images stored in /hdocs/www/img/ right now (of course i could move them, and fix all references to them) but I like them there because I can refer to images in pages in /www/ with background="img/bgpic.jpg" ...of course this works just fine becuz /img/ is just down from /www/. but now I have pages in subdomains as menitoned above like: /htdocs/util/showdatabases.php and of course I want to refer to images from those subdomain pages too,,and of course I don't want to have another dir with the same pics in them..something like... /htdocs/util/img/ becuz I already have the pics in /htdocs/www/img/ and if I make another sub domain called /htdocs/stuff , I don't want to have to copy the pics AGAIN into /htdocs/stuff/img right? So,,, (yes I may be getting to the end now..) how or where should I put my pics so the /www/ and /util/ and /stuff/ guys can use them as background pics? what would the body tag look like? <body background="../www/img/background.jpg"> doesn;t work what will? <body background="What??????"> thanks again, Ken
