That's because physical size has -absolutely nothing to do with pixel  
count-.  You can make a scan of a 35mm slide at well over 1600DPI,  
make a giant 72DPI poster from it, and a 300-600DPI proof.

Most photo services don't recommend trying to print anything below  
150DPI, as jaggies appear.  It is generally a good idea to make  
anything you want to print either 300 or 600 DPI, or some even DPI,  
as the printers usually have a kind of half-assed down-rez algorithm  
designed for speed, not quality.  On larger prints, you should also  
watch to not over-sharpen images.  What looks like a nice  tack-sharp  
image on a monitor will look like hell on a print unless viewed from  
beyond-arms-length.

See if there is a port or GUI interface to "imagemagick" (a Unix  
utility which probably runs in at least command-line form on Windows.)

IrfanView might also do what you're looking for.

If you want a photoshop-ish program, grab GIMP (www.gimp.org.)
