[Javascript] An image loader working in FF but not in Opera, Safari...

[Hakan]

Hi Guillaume,

Two things:

 >     var img = content.getElementsByTagName("img");
 >
 >     if ( img.complete ) {

getElementsByTagName returns an array with the nodes matching the tag 
name. This array doesn't have a "complete"-property, and I'm guessing 
that the only reason this "works" in Firefox is because it will get here 
on window load and, since both conditions hide the loading div, it gets 
hidden.

 > window.onload = checkDone;

When this triggers, images should already have been loaded.

I'm sorry, but this script seems to do nothing.

Regards,
H
