You can either:

   (1) store the bytes of the image itself in the DB.
   (2) store it somewhere in the filesystem, and store its location in the
DB.

   To give the image to the user:

   (1) Have the HTTP server respond to the URL request by connecting to the
DB and returning the bytes of the image, instead of HTML data.
   (2a) Link directly to the file on the file system if the file is in a
location that is shareable.
   (2b) Have the HTTP server respond to the URL request by reading from the
file and returning the bytes of the image, instead of HTML data.
