if you are running windows xp...a free resizer from microsoft is available...looks easy to run http://www.wikihow.com/Easily-Resize-Photos-in-Windows-XP
warning...it has known compatibility issues....it is not supported by microsoft... but I have installed it anyway to see if I can make it work on windows 7..... no...it will not work
but good news....I inadvertently found I can easily resize images from the free 'paint program running on my machine.... daah... I am a dummy sometimes heres the link to paint... **but note it does not support RAW images
It supports common image formats--JPEG, PNG, GIF, TIFF, and others--but not high-resolution RAW files
