Image Component stretching the src image!

Hmmm. Not sure what else to show. I find Animate to be VERY difficult to find rhyme or reason as to when something can be styled with a css style or not. I also find it extremely difficult as to how to target an instance Sometimes I can do it with "this.movieclip" Sometimes I have to target with "exportRoot.moviclip". This program needs some major consistency and documentation.

Here is my function which swaps the image (the image component is manually placed on the stage. :

function showBigImage(e){

     this.myImage.src = "";

//imgSrc[] refers to an array which holds all of my image source paths

//When calling this function, e is a number to reference in the array.

     this.myImage.src = imgSrc;

     exportRoot.myImage.x = 100;

     exportRoot.myImage.y = 65;

     document.getElementById("myImage").style.width="75%";

     document.getElementById("myImage").style.height= "auto";

}
