You can also resize your photo with microsoft photo editor. Just open your photo using MS photo editor. On the drop down menu click on "image" then click on "resize". A window will open showing you the current size of your photo. Use the up/down arrows by the size box to change the size or enter a new size in the box. Make sure the units are set to pixels. 640 X 480 seems to work good for uploading to this site.
