You cannot do it with only CS3...there are addon that you can buy to do that. One called onOne Genuine Fractals, which is a plugin in CS3. Or you can buy PhotoZoom Pro, a separate application by itself...it works wonder. I tried/use both. Depend on what I'm working on.

it's impossible to increase the size of a picture without decreasing the quality. You may be able to reduce the amount the quality is decreased by going to image%26gt;image size and setting the resample image to bicubic. It might help a little, but it will still loose quality.
Unfortunately, you don't... short of retouching them after a resize.
