SlideShow as3

programming flash

Hi. I’m new to AS3, and I have a class file that displays a slideshow and preloads each image in an xml file. the code is below. What I want to know is, is there any way to improve this code? The code works, but I feel like I’m doing it wrong. Any help would be appreciated. Thanks.

package {
