Does anyone use Flash utilities of Flagstone Software?
http://www.flagstonesoftware.com/

On their page there is an example of how to pack an image inside a flash (and
show it):
http://www.flagstonesoftware.com/code/Example.java
http://www.flagstonesoftware.com/code/ShowImage.java

I wanted to extend that by making a movie out of a series of images. I thought
that all I had to do is create a list of Files and use ShowImage's code inside a
loop. The result is not as expected. A .swf file is generated but when I want to
play it, only the first image is shown. Can anyone tell me what am I doing
wrong? Or what am I not doing that I should?

Here's the code:
