How do I resize my image?
Open your image in Microsoft Paint. This program can be found from your desktop by selecting 'Start' -> 'All Programs' -> 'Accessories' -> 'Paint'
In the menu bar at the top of the program, select 'Image' and choose 'Stretch/Skew':
That will open this dialog box:
Now, put in whatever percentage you would like your image to be changed to. Keep in mind that
100% is full size, so 50% would shrink the image to half size, and 200% would expand it to twice
the original size.
After you've found a size that works, save the image and upload.
