Need some advice

I need to build a site that will show images , in flash. There will be a main menu with different categories. When I choose a category images will show. Inside that category I can click an image and sub images for that image will show.

My question is what would be the easy thing to do. XML coding or a db working with the flash file using PHP etc.?? Any books or tuts to recommend on how to build something like this.

Im not a noob , but no expert either… :sigh:
