Standard approach is putting the files outside the webroot, and running requests for a file through a script - that script then does whatever authentication is required, and outputs the image as required. There are some examples on the php man page for readfile(). A quick way of doing the link is having something like /serve.php/file.jpg and using $_SERVER["PATH_INFO"] to look up a file to grab. Other approaches are things like mod_rewrite. -- E|2 DIGITAL TIM OLIVER SOFTWARE ENGINEER P +64 3 377 0007 F +64 3 377 6582 E [email protected] www.e2digital.co.nz --~--~---------~--~----~------------~-------~--~----~ NZ PHP Users Group: http://groups.google.com/group/nzphpug To post, send email to [email protected] To unsubscribe, send email to [email protected] -~----------~----~----~----~------~----~------~--~---
