Retrieving and Showing an Image from a Database
In this example, the image is created from the Image field in the Images table from the Northwind database on-the-fly and once again is never saved to hard disk. Then, the image is displayed using the Image server control. We will use one Web Form to create and implement an image, and another to display it. Listing 13.6 contains the image Web Form, which will retrieve the image from the database and create a Web-usable image.
