I am creating a custom class called Image.
When called from a SWF it constructs the box and text as it is supposed to, but I also need to call an image into the object but that isn’t happening.
Here is the code for the class:

Here is the code inside of the FLA:
var btn1:Image = new Image();
btn1.label = “Weatherization Weatherization Weatherization”;
btn1.myImage = “w.png”;
btn1.fontColor = 0xFFFFFF; //white
btn1.width = 100;
btn1.height = 100;
btn1.fontSize = 11;
btn1.bkgdColor = 0xFF0000; // red
btn1.x = 200;
addChild (btn1);
I have the png file in the same folder as the FLA and class so the path should be correct. It is constructing the properties from the FLA correctly, except for the image (png), which is absent. It isn’t outputting any errors, but the output box spits out 8 of the trace (“this is hard”) from the loadImage (); function. I’ve included a zip file with everything I have. Thanks in advance for any help anyone could provide.
