URLRequest for external jpegs

programming flash
1

Hello…

This should be simple but it has had me stuck for a while.

I’m trying to click a button or thumbnail to open a jpeg. The jpgs are external and bigger than the stage dimensions.
When previewing the swf, it works just fine. The jpegs open in Preview. But… when the swf is embed in the html file, the jpeg can’t be located. Is there an issue with the my code or is something. Here is some sample code:

zagat_btn.addEventListener(MouseEvent.CLICK, zagatThumbFunction);

function zagatThumbFunction(e:MouseEvent){
	navigateToURL(new URLRequest("zagat.jpg"));
}
