Suzanne: If you have Adobe Photoshop there is an add-on/plug-in called "genuine fractals" from lizard tech. It does a fine job of increasing the number of pixels. It doesn't actually improve resolution but allows 'zoom in' without immediate pixelization.
Mostly use it for more clearly defining edges. It can turn a 1mb file into an 6mb quite quickly. I belive there is a trial period. Can be downloaded from lizardtech.com or whatever their address is. If you don't have photoshop, you can download photoelements from adobe. There is a 30 day trial period, if you like it its dirt cheap. Fractals works with it also. Regards Roy N.
