Array question

Is there another way to write this array in AS2?:

var img_array:Array = new Array({img:"nav_thumb1", img:"thumb_01"}, {img:"nav_thumb2", img:"thumb_02"}, {img:"nav_thumb3", img:"thumb_03"});

This is pretty simple, but when you need more values inside each element, it gets difficult to maintain.

I know I could probably do this using XML, but I’m trying to learn all about arrays

Thanks!
