How to apply glowfilter to an external GIF file

Hello,

I am trying to load an external transparent GIF file with
loadMovie("mypicture.gif", container);

I made on the stage a movieclip with the instance container. When i manually apply a filter to this movieclip
and when the picuter is loaded in this target you don't see a glow.

Perhaps it should be done by actionscript, does anyone know how?

Regards,
Micheal
