Why is there a difference? (jpeg)

Hello. I’m new.

I know the problems with flash and jpeg. But this problem I don’t understand:

I have a picture gallery in a swf file. With LoadMovie you can load a new swf file with jpeg into the screen. If you open this link:

http://www.mostpopulardj.nl/PHOTOS/PERRY_1.swf

you see the photo in quality, but if you load this movie into the mother movie, the quality is gone…

Why? Anyone?
