Superimpose text over blank image

Wrote this online little tool so anyone can create a blank image with a background color of your chosing (defaults to black) directly from my site. With your choice of color text super-imposed over the blank image (defaults to white). See the url. The image can then be saved for use on web sites, or in emails, etc. Or reference directly from your web page. Using AJAX with PHP to perform the submission. The code is available at the download url.
