your update page has the same code order problem as before.
the code order is:
recordset
set session value
update record
the order should be:
update record
recordset
set session value
also, on the client-home.php page, you are creating a recordset, why not filter that recordset on the SecurityAssist_UserID session variable, and use the recordset for displaying the image instead of trying to store the file name in a session and change that on update.
