Can someone tell me how to do this?

Hello, I am new to using flash and also this forum. Before I ask my question, I would like to say what an honor it is to communicate with flash and flash design experts such as yourselves. I just need to know how to make a flash banner almost exactly like the one in the link. I would make it my own of coarse, but I need my banner to be the same size and same effect when the pictures change.

I need to know how to make the photo's change from one to another, and how to make the transition effect as the photo's are changing.

Here's the link to the banner I need to know how to make.

Any information regarding how to make this, including tutorial videos or articles, would be very much appreciated.
Thank you all so much for the information and advice.

it would take a bit of figuring out, but you will need to use layer masks, however you look at it.

If you're new to flash, you'd better try something simplier to begin with. But if you wanna start learning complicated animations right away, read AdvancED Actionscript Animation book by Keith Peters. Especially chapter 9, PIXEL BENDER. That's a really good stuff even though it might be way too difficult for the beginner
