FrogJS - Make new thumbnails appear on the left, and old ones on the right

[Berlo]

1) Script Title: FrogJS Image Gallery

2) Script URL (on DD):
http://dynamicdrive.com/dynamicindex4/frogjs/index.htm

3) Describe problem:

Currently, the new thumbnail appears on the right of the main image, and the old thumbnail appears on the left side of the image.
How can I make it work the other way? New on the left, old on the right?

Thanks!

Find these:

		var rThumb1 = document.createElement("img");
		rThumb1.setAttribute('id','FrogJSrightThumb1');
		rThumb1.style.display = 'none';
		rThumb1.style.position = 'absolute';
		rThumb1.style.top = thumbTop;
		rThumb1.style.right = '0';
		rThumb1.style.cursor = 'pointer';
		ribbit.appendChild(rThumb1);
		
		var lThumb1 = document.createElement("img");
		lThumb1.setAttribute('id','FrogJSleftThumb1');
		lThumb1.style.display = 'none';
		lThumb1.style.position = 'absolute';
		lThumb1.style.top = thumbTop;
		lThumb1.style.left = '0';
		lThumb1.style.cursor = 'pointer';
		ribbit.appendChild(lThumb1);
		
		var rThumb2 = document.createElement("img");
		rThumb2.setAttribute('id','FrogJSrightThumb2');
		rThumb2.style.display = 'none';
		rThumb2.style.position = 'absolute';
		rThumb2.style.top = thumbTop;
		rThumb2.style.right = '0';
		ribbit.appendChild(rThumb2);
		
		var lThumb2 = document.createElement("img");
		lThumb2.setAttribute('id','FrogJSleftThumb2');
		lThumb2.style.display = 'none';
		lThumb2.style.position = 'absolute';
		lThumb2.style.top = thumbTop;
		lThumb2.style.left = '0';
		ribbit.appendChild(lThumb2);

Replace them with these:

		var rThumb1 = document.createElement("img");
		rThumb1.setAttribute('id','FrogJSleftThumb1');
		rThumb1.style.display = 'none';
		rThumb1.style.position = 'absolute';
		rThumb1.style.top = thumbTop;
		rThumb1.style.right = '0';
		rThumb1.style.cursor = 'pointer';
		ribbit.appendChild(rThumb1);
		
		var lThumb1 = document.createElement("img");
		lThumb1.setAttribute('id','FrogJSrightThumb1');
		lThumb1.style.display = 'none';
		lThumb1.style.position = 'absolute';
		lThumb1.style.top = thumbTop;
		lThumb1.style.left = '0';
		lThumb1.style.cursor = 'pointer';
		ribbit.appendChild(lThumb1);
		
		var rThumb2 = document.createElement("img");
		rThumb2.setAttribute('id','FrogJSleftThumb2');
		rThumb2.style.display = 'none';
		rThumb2.style.position = 'absolute';
		rThumb2.style.top = thumbTop;
		rThumb2.style.right = '0';
		ribbit.appendChild(rThumb2);
		
		var lThumb2 = document.createElement("img");
		lThumb2.setAttribute('id','FrogJSrightThumb2');
		lThumb2.style.display = 'none';
		lThumb2.style.position = 'absolute';
		lThumb2.style.top = thumbTop;
		lThumb2.style.left = '0';
		ribbit.appendChild(lThumb2);

I Thank you again for all your time.
You have helped me much.

As you know JS so well, do you have your own scripts?
