First of all you need to program the server to be able to serve you partial/scaled images of you "giant" picture. Let's say, you need to able able to say: "give me a subpicture that starts at (X0,Y0) and end at (X1,Y1) with a scale of SCALE.

It would be good to create cache on this.

Then you have to program a flash that is able to communicate with this server, asking him for the appropiate images in the appropiate moment.

It is recomended that you make your flash get bigger areas of the image that you are vieweing so you can pan and zoom right away and have something to show before you start loading the rest of the images.
