Q737 How can you retrieve efficiently an images position in the document.images array?

By looping through the image object looking for an image with a name property equal to the one you are searching for:

<SCRIPT LANGUAGE="JavaScript"><!--
var position = -1;

for (var i=0;i<document.images.length;i++) 
    if (document.images[i].name == 'thisone') position = i; 
//--></SCRIPT>
