Images look funky when I import them into flash

They have a dirty, slightly blurred look to them. I was wondering if someone knew an actionscript code that allowed you to load up images from an external source of the Flash page. Like what I would do is save segements of my actual interface into gifs, then type up some code in actionscript that loads up the images on the fly within my flash document. Sounds like scifi, but wondering if that is possible.

Or, if I can’t do that then what image settings should I create in Adobe Photoshop to prepare my interface for Flash? 95% of my interface will be constructed of Flash vectors, but the header of my interface is a pattern design.
