ultimate fade in slide show 2.1 screen error

[wordwood]

I have installed this slide show codes in my blog to light the christmas tree. however, the tree has outer black jacket as you see in the above site. I have followed the directions that were written. How could I make a neat surface of the tree slide? To be sure, the original images have no black dirts.
Script URL: http://www.dynamicdrive.com/dynamici...nslideshow.htm

I edited several parts for application.

1. embedding script
1) changing size: dimensions: [130, 252]
2) image array: 11 images
3)display mode: {type:'auto', pause:100, cycles:0, wraparound:false, randomize:true}
4)fadeduration: 500
2. background to transparent in fadeslideshow.js

setting.$gallerylayers=$('<div class="gallerylayer"></div><div class="gallerylayer"></div>') //two stacked DIVs to display the actual slide 
			.css({position:'absolute', left:0, top:0, width:'100%', height:'100%', background:'transparent'})
			.appendTo(setting.$wrapperdiv)

You can compare the original image slides using flash with this javascript-applied slides in this link.
