try this.
For those using Windows XP, there is a free download from Microsoft called ImageResizer. Once you install the program all you need to do is right click on the file(s) you want to resize and select the new size. Using this tool the full size photos from my camera, resized to 800x600 are also reduced in file size from 1 meg to 100k or about 10%.
Here is the link to the software.
