How_to_display_JPG_files_that_are_stored_on_the_user

You've had a lot of replies saying that you can not
do this in PHP

While the PHP Script can't do it alone,
you can embed client side code to meet the need.
Several users suggested Java.

If you are open to an ActiveX solution ( requires browser
to be IE on Windows system ) then this becomses easy.
Our MetaDraw control can display local ( or remote)
JPGs ( or other image formats ) within a scrollable,
zoomable client side window. Also in Active X it
is easy to handle the directory listing and file
deletions ( if allowed by the user ).
