document.images[nt_01] does reference a specific object, but you cannot 
alert() an object. You can alert an attribute of an object. 
alert(document.images['nt_01'].name) would get you what you want. Also, 
note the ' ' used. images['img_name'] is an associative array, so you  
need quotes. The example I sent you placed the name of the image in a 
variable first:

var next_image = "nt_01";
alert(document.images[next_image].name);

No quotes are needed in that example.
