Don't think your images are going to look very good at 70 inches at either 72 dpi or 150 DPI. They will look horrible at 72. How big are your files right now? You'll need to run them through Genuine fractals, but you should have at least 20 megabytes per image to res up anywhere near 70 inches. Even then, it would only look sharp from many feet away. If your files are a 80 to a hundred megabytes now, you should have no problem. These are just ball park figures.
