Your basic options are these:
1. Use a BLOB datatype to store the images directly in the database.
2. Use filesystem pointers to store the image in a file, which is retrievable
through your interface code.
For a variety of reasons, I prefer 2. However, the BLOB approach as strong
adherents. See the Postgres docs for more info:
