Problem with loading multiple images

programming flash
1

i want to make a thumbnail scroller therefore i need multiple images loaded.
loading the pictures is not a problem.
what i need is, i want to treat these images like any DisplayObject; meaning i need to use width, height properties or i want to add event listeners, which i cannot do at the moment
here is my code(for example, i need the property in red part):

 function thumbLoad() {
    for (i=0; i<len; i++) {
        array*=new Loader();
        array*.x=index;    
        array*.y=2;    
        [COLOR=Red]index=index+4+array*.width;[/COLOR]        
        array*.load(new URLRequest(thumb*));
        Frame.addChild(array*);    
//Frame is the movieclip i load the images on    
    }
}
