Photoshop CS3 - How do I make a jpg images larger and still maintain clarity?

[wildmick21]

I have several jpg images that I need to increase the size of - and everything I've tried produces jagged edges and distorted results. I have Photoshop CS3, and I've searched online for hours looking for a simple list of directions to do this without success. Can someone point me in the right direction?

Unfortunately, you don't... short of retouching them after a resize.

What happens when you click on Image > Image Size?

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>image size and setting the resample image to bicubic. It might help a little, but it will still loose quality.

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.
