Hello. We can set a background image for a html tag:
#example_div{
background-image:url("http://example.com/example.png";);
}
Now when the html page is retrieved, a request will be opened for
background image file. But how can I add an observer that will notify
me when the background image file is completely downloaded?
Thanks.
