Well I just take my high-res pictures and use the XP tool called ImageResizer its free here:

And just right click on my picture I want to use and pic custom and pick a size like 150X120 or so pick what you like and keeps the photo about right, just get something you like and remember for the next time pretty easy to use and has nevered failed me yet no need to use a big program like photoshop just to resize a picture real quick.
Enjoy
