This tutorial found on:

The problem manifests itself when I substitute .jpg thumbnail with .swf one.

[color=silver](I need this because i need transparent thumbs, so i needed to import transparent gifs via swfs - i used [/color][[color=silver]http://www.quiss.org/swftools/[/color]](http://www.quiss.org/swftools/)[color=silver] to convert gifs to swfs if someone is interested - It is released under the GPL. )[/color]

XML is parsed ok, and the thumbnail is visible with other .jpg thumbnails. The problem is that it is not “alive”:

Clicking on it doesn’t change the main image, hovering doesn’t change its alpha:  
[color=red]target\_mc.onRelease = function() {  
p = this.pictureValue-1;  
nextImage();  
};  
target\_mc.onRollOver = function() {  
this.\_alpha = 50;  
thumbNailScroller();  
};  
target\_mc.onRollOut = function() {  
this.\_alpha = 100;[/color]

Here is portion of XML:  
[color=red]\<pic\>  
\<image\>images/72.jpg\</image\>  
\<caption\>Nathan Never 72\</caption\>  
\<thumbnail\>images/t\_72.swf\</thumbnail\>  
\</pic\>[/color]

Anyone have ideas?

I thought that there is no difference between .jpgs and .swfs once imported.
