i was loading images dynamically, but as they are loaded on top a button placed in the movie is overwritten, but - it workes like this:
one blank movie 'movJpg' for the jpg's within a movie with a button 'movBut'
now you can duplicate movBut movie as often as you like, and load lots of pictures it it's 'movJpg'...
you can animate and everything, and they behave still as buttons!
i like actionscripting!
