Your image must be a GIF, PNG or JPEG file that is less than 25k in
size.
Your text can go here, up to 500 characters.
It can contains the following
HTML elements only, <font> <a> <b> <p> <br> <hr>.
The height + the width of the image must be less than 500 pixels.
You will also be able to select a solid color for the background.
We recommend you don't use transparent images, as Internet Explorer still
does not handle them correctly.
