@Skiracer901authorJun 18.2003 — I mean how to tell if the image is loaded in javascript! I want to make a script that changes the image if it didn't load properly.

@pyroJun 18.2003 — How about something like this:

var img = new Image();
img.src = "http://www.yourdomain.com/images/img.png";
img.onerror = function () {
//swap the image
}

var img = new Image();

img.src = "http://www.yourdomain.com/images/img.png";

....

if ( img.complete ) {

//image has been downloaded now

} else {

//image has not been downloaded

}

@ZeroKilledNov 20.2007 — the property complete is propietary of msie only and doesn't work on firefox. using the attribute complete isn't recommended.

Looks like w3schools has done some testing on that as well
