just fill the prices into all those boxes shown. and from that point on, all it will fill everything in each time.
bulk edit, hit bulk, show all images, there is an empty box on the top list hit that, then directly below that one, it will have another box that shows all your images. after that's checked, then hit the button that lets you edit. check off the items you want to change prices on. add new prices, hit ok and wait.
