Dynamic movie clips

I am very new to flash. I would like to learn the capabilities of Flash.

Can you generate dynamic movie clips from JPEG messages received from an XML file? I mean can I refer to these movie clips as any other static movie clip instance created with the flash library?

What exactly do you mean by JPEG messages? You can read and dynamically load JPEGs into movieclips created by actionscript.

Sorry, I meant JPEG images obtained from XML messages. I just wanted to confirm the following:

I create a static movie clip with the .fla and add it to the library. Then I can refer to this movie clip any time anywhere.

Can I assign a JPEG image to a dynamically created movie clip instance say in an ActionScript class which could be referred anywhere at any time?

I hope I am clear in my question.
