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

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

The web page is located at
