Before uploading:
1. Re-size each image to under 500px width by 500px height.
2. File names are case-sensitive and can not include spaces.
Maximum file size = 800 KB
You may upload .jpg or .gif files.
You must also enter the exact file name in "Add" or "Edit" form,
so it is a good idea to save the file with a short name such as "mylogo.jpg"
