   5  Our web service provides custom images.  The client may specify a text 
   6  message to appear on the image, and receives it as an array of bytes 
   7  representing a jpeg file.  Additionally, the client may choose to send 
   8  the image as an email to a specified SEAS address.  The web page allows 
   9  you to specify message text as well as all parameters for an email.  
  10  Additionally it provides a dynamic image file that returns the image 
  11  to a web browser.  This image URL can be used by users of the web 
  12  site.  The web service does not use that image for the emails since 
  13  it shouldn�t be depending on one of its clients.  It instead embeds 
  14  the jpeg file in the email itself which is where we spent the 
  15  majority of our time.

  17  The service is located at http://harbormist.com/webservice/AddTextToImage/Service.asmx
  18  We changes all of the default file names but left Service.aspx alone 
  19  because that seems to be a standard place to look for the WSDL. The 
  20  source is in the DynamicImageGenerator folder in this zip.
