Assuming you wish to display the images on a web page, you would need to
extract the image from the database and write it to disk as a jpeg,gif
or png image. The web page can then display it through an img tag.
Alternatively with HTML5, you could try extracting the image and
displaying it in a canvas element which would be a fun project.
