you would need to create a table to store the file names of the photographs, and the ID of the user they relate to:
photgraphID - primary key
photographUserID - relates to users.userID
photgraphImageName - stores the file name "123.jpg" for example
when a user logs in, their ID is stored in a session variable.
Use a recordset to query the photgraphs table and filter the photographUserID on the session variable that is set by login.
use this recordset to populate the page with images.
