If you are using Windows XP there is a small program from Windows that I found is great for resizing pictures.It's called image resizer.Just go to www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
and download the small program.Then right click the picture you want to make smaller and choose from the 3 choices it gives you.I've used this program for years now.Hope I could help...
