Actionscript 3 :: Duplicating External Items Into An Array?

If i was loading external content, such as images or what not will the array load the items twice for example:

load = array(){
load images( "local/folder/www.example.com/" );
items("car.jpeg","bike.jpeg","bike.jpeg");
}

The above is in theory, if you notice twice i have the "bike.jpeg" image in the array; its key value would be either items[1] or items [2].

so with the above idea in mind would this bike image be loaded twice or just referenced in the array from the first initial load.
