Thanks to Zane, Winston, Bernard, Ken. I installed Vuescan. I must be doing something wrong. The pictures scanned look like a slide instead of a picture. and it only scanned 2 even though I had 4 slides in the scanner. Do I have to purchase to get it to scan 4 slides? It gives me lots of options which I am not familiar with.
