Hi people! I would like that somebody told me about how you do to handle assets dynamically.

My situation is this: Im creating a library to use as a shared one by several other swf files, the library contents graphics which content images. I need to attach different graphics in a dynamic way. Ive seen that if I put the graphics on the stage, it works...but... is there any other way to do this.
Can I import audio assets and attach it dynamically.
Why I cant assign actions to imported buttons?
