I basically have a colour advertisement taken from a magazine. The ad is roughly 4" x 6". I would like to at least double the size of the image. Is there a way for me to scan this image and enlarge the image with minimal distortion? Are there any editors that will automatically try to fix the distortions???
I know it's a long shot but I thought I'd ask anyways.

You cannot make an image larger with out loosing quality, unless it's a vector. In your case it's not. GIF, JPEG, BMP will all loose quality when resized.

I pretty much gathered that. I was asking just incase there are applications out there that might automatically alter it so it's not as distorted.

You can try scanning it at a very high resolution.
Then, enlarge the size of the image using photoshop.
There's going to be distortion, but you might be able to pull it off.
Then if you use a slight blurring technique, and sharpening other edges of what you want to be the focal point of the image, you can make a pretty decent enlargement of the original without sacrificing too much quality I think.

Aren't there methods of interpolation (ie: fractal interpolation) that "adds" lost detail to the enlargement? It doesn't really add detail that wasn't there to begin with, but with certain methods of interpolation, it is able to take guesses at whats supposed to be there. To my knowledge, fractal is the most powerful one out there (although it leads to very "fractalish" images, you will have to google an image to see what I mean).

Try PhotoZoom Professional (http://www.benvista.com/main/content/content.php?page=ourproducts§ion=photozoompro_1)
It uses the S-Spline algorithm to interpolate pixels during the enlargement ... trust me, I have done A LOT of research ... this is where its at.
Used by most professional photographers

He doesn't need image enhancement software, he just needs a good scanner.
Know anyone in publishing? Beg borrow or steal some time on one of their professional drum or flatbeds.

Your biggest challenge isn't interpolation, but dealing with the enlarging the moire-pattern (the CMYK rosetta that use for printing) - most pubs are printed @ 133-150 line and doubling that is going to give you a really coarse 65-75 line screen - the descreen function on most scanners is hit and miss.

I don't have a great scanner. It's a HP all-in-one.

Do I need special software to adjust the resolution of the scan? Or do I do it from the scanner?

This might not be what you're looking for.. but.. if you found it in a magazine, there could be web ads out there somewhere too, in better quality :)
