How can I create a photo gallery in flash cs3, Iam a beginner in flash

How can I create a photo gallery to put into my current flash site Iam creating? Using  flash cs3, can anybody suggest any tutorials (noting complicated with me being new to flash cs3)

When going on line I saw that maybe you can use Dreamweaver, XML, or even Photoshop can anybody explain the difference between using one or the other?

THanks
