Making a rotated image look nice

Does anyone have a method for rotating an externally loaded image that doesen’t make the picture look awful?
I have browsed the forums and I see this is a common problem, however I haven’t found a nice solution to do this in AS3. Editing each image in photoshop unfortunately isn’t an option for me. :frowning:
I’m guessing this would have something to do with programatically smoothing the image after it’s loaded, however i’m kinda new to AS3 so I could be totally wrong.

I would be really thankful for any pointers.
