I've got a question pertaining to fading

I’m pretty new to flash, and this website has been quite helpful, but I’m still kind of lost.
I read through the fading text tutorial, and though it was talking about text, I figured out how to import an image and make it fade from that. But I’m trying to get a second image into the same flash movie file, so that it will fade into one image, then fade to blank, then fade to another image, fade to blank again, and then start over, and I can’t figure out how to get the second image to work, once I’ve got the first to fade out. I’ve tried to just import the second image, and then create motion tween, and it doesn’t work.
I apologize if this is a really stupid question, or if there’s a tutorial around the site covering this and I’ve missed it, but I’m new to all this, so it’s kind of foriegn to me.
Could someone help?
