Help me buy a grapics program (for manipulating scanned images)

[hobbes9324]

I (being an old guy) could use some advice from my more computer savvy OOT'ers on buying a program that will let me manipulate graphic images (mostly JPG and BMP)

Windows based.

Mostly for scanning postage stamps and envelopes and enlarging/manipulating.

I've been using CompuPic, but am looking for something better.

Thanks!!
