What is a good way to P&D my Project?

I have a game with hundreds of graphic and map files. Should I put all of these in a resorce file so they are compiled into the .exe and then Package them or should I add them as files in the P&D Wiz and put them into directoties like\Images and \Maps?

Any general packaging advice would be helpful as I have never run my games on anyones computer but my own? I don't really know what to expect in the way of problems.

Thanks

I once had to ship 100 images with an app, I left them in a folder (not in a resource file) because I wanted to allow the user replace my images.

If you hard coded the image names i would put them in the exe, but if you want to do like Robby and allow the user to change them make sure that you check the names or you will get error messages
