restacking thumbnails

[Pants234]

i am creating a small image gallery and am slowly hacking my way through learning AS3 at the same time. I want the thumbnails to overlap each other and when a new one is clicked, it pops to the front and the other thumbs restack and resize appropriately. I have some hideous code here to demonstrate. It works, but is clearly not that way to go code-wise. Can anyone point me in a direction here on how to clean this up?

currentElement.width = 74;
currentElement.height = 96;

if(currentElementNumber == 0){
	setChildIndex(elementsArray[0], 1);
	setChildIndex(elementsArray[1], 1);
	setChildIndex(elementsArray[2], 1);
	setChildIndex(elementsArray[3], 1);
	trace("currentElementNumber: " + currentElementNumber);
	elementsArray[1].width = 64;
	( elementsArray[1].scaleX < elementsArray[1].scaleY ) ? elementsArray[1].scaleY = elementsArray[1].scaleX : elementsArray[1].scaleX = elementsArray[1].scaleY;
	elementsArray[2].width = 54;
	( elementsArray[2].scaleX < elementsArray[2].scaleY ) ? elementsArray[2].scaleY = elementsArray[2].scaleX : elementsArray[2].scaleX = elementsArray[2].scaleY;
	elementsArray[3].width = 44;
	( elementsArray[3].scaleX < elementsArray[3].scaleY ) ? elementsArray[3].scaleY = elementsArray[3].scaleX : elementsArray[3].scaleX = elementsArray[3].scaleY;
} else if (currentElementNumber == 1){
	setChildIndex(elementsArray[1], 1);
	setChildIndex(elementsArray[0], 1);
	setChildIndex(elementsArray[2], 1);
	setChildIndex(elementsArray[3], 1);
	trace("currentElementNumber: " + currentElementNumber);
	elementsArray[2].width = 64;
	( elementsArray[2].scaleX < elementsArray[2].scaleY ) ? elementsArray[2].scaleY = elementsArray[2].scaleX : elementsArray[2].scaleX = elementsArray[2].scaleY;
	elementsArray[0].width = 64;
	( elementsArray[0].scaleX < elementsArray[0].scaleY ) ? elementsArray[0].scaleY = elementsArray[0].scaleX : elementsArray[0].scaleX = elementsArray[0].scaleY;
	elementsArray[3].width = 54;
	( elementsArray[3].scaleX < elementsArray[3].scaleY ) ? elementsArray[3].scaleY = elementsArray[3].scaleX : elementsArray[3].scaleX = elementsArray[3].scaleY;
}else if (currentElementNumber == 2){
	setChildIndex(elementsArray[2], 1);
	setChildIndex(elementsArray[1], 1);
	setChildIndex(elementsArray[3], 1);
	setChildIndex(elementsArray[0], 1);
	trace("currentElementNumber: " + currentElementNumber);
	elementsArray[0].width = 54;
	( elementsArray[0].scaleX < elementsArray[0].scaleY ) ? elementsArray[0].scaleY = elementsArray[0].scaleX : elementsArray[0].scaleX = elementsArray[0].scaleY;
	elementsArray[1].width = 64;
	( elementsArray[1].scaleX < elementsArray[1].scaleY ) ? elementsArray[1].scaleY = elementsArray[1].scaleX : elementsArray[1].scaleX = elementsArray[1].scaleY;
	elementsArray[3].width = 54;
	( elementsArray[3].scaleX < elementsArray[3].scaleY ) ? elementsArray[3].scaleY = elementsArray[3].scaleX : elementsArray[3].scaleX = elementsArray[3].scaleY;
}else if (currentElementNumber == 3){
	setChildIndex(elementsArray[3], 1);
	setChildIndex(elementsArray[2], 1);
	setChildIndex(elementsArray[1], 1);
	setChildIndex(elementsArray[0], 1);
	trace("currentElementNumber: " + currentElementNumber);
	elementsArray[0].width = 44;
	( elementsArray[0].scaleX < elementsArray[0].scaleY ) ? elementsArray[0].scaleY = elementsArray[0].scaleX : elementsArray[0].scaleX = elementsArray[0].scaleY;
	elementsArray[1].width = 54;
	( elementsArray[1].scaleX < elementsArray[1].scaleY ) ? elementsArray[1].scaleY = elementsArray[1].scaleX : elementsArray[1].scaleX = elementsArray[1].scaleY;
	elementsArray[2].width = 64;
	( elementsArray[2].scaleX < elementsArray[2].scaleY ) ? elementsArray[2].scaleY = elementsArray[2].scaleX : elementsArray[2].scaleX = elementsArray[2].scaleY;
}

Each of your cases seems to be identical except for the indices. Figure out how to derive the proper indices from the currentElementNumber and collapse your cases down to one. I don't know what you mean by getting the other elements to restack appropriately, but setting them all to child index 1 is not the way to go. That basically sticks each one at the second lowest depth (pushing the previous ones out of the way in the process).
