Photo Organizer

When a logged-in user clicks on 'subscribe and become a client of this user', the returned html says:

"If you like these images you can register and see the protected images of ."

- because $user_display_string is not defined in subscription.add.php

this modification seems to fix it:

if (!$make_client_request) {
$user_display_string = disp_user_string($database, $user_id);
print "<p>";
print $strings['users']['confirm_subscription'] . " $user_display_string.\n";
print "</p>";
}
