.jpg bground image through IIS server

I have a html page hosted through IIS server. This html page uses .jpeg image as a background image (Using the html tag ). When I open this file by directly doubleclicking it (In IE), background image appears. But when this page is hosted through IIS server and is accessed (Using its URL like http://abc/xyz/myhtml.html), then background image doesn’t appear. Does anybody know why .jpg image doesn’t appear in the background when html page is hosted on a IIS server? And how to sove this problem ?
