I've created an image in low resolution that I CANNOT recreate in high resolution. Even running through the same steps with the same program it comes out looking very different. I was wondering if anybody knew of a program that can take a low resolution JPG and convert it to a higher resolution. I know that this can be done as I've seen it with my own to eyes but this was on a piece of sign writing software that is far more powerful and expensive than I need.

Not to argue, but as you state it, it is not possible.

You can enhance a picture. For example, photo-shop filters can sharpen and otherwise change a picture.

Unfortunately, you can not create information that does not exist.

To boost a low-res picture to a high-res one, you'd have to find the missing information. Because it has been lost, you can't compute it.

BTW, one sees such a magical transformation constantly in the movies!

Actually I found a program that does it. It's called focus magic. It's not brilliant but it does quite a good job. It uses some sort of algorithm to work out where which colours are supposed to be.

You can improve low res images using Genuine Fractals software. It will actually do a great job of enlarging your image and not creating a bunch of "white noise" in the process. You can go from 72 dpi to 300 dpi.
