If you just want to prevent users from getting a listing of your image
directory, you can do a couple of things:

1) Put an empty 'index.html' (or whatever the server default is) in the
image directory, so anyone trying to browse the directory will get a blank


2) (Assuming your server is Apache) Create a '.htaccess' file in the images
directory and add the line

Options -Indexes

Either one ought to be less of a performance hit than doing a readfile() on
each image you want to send to the browser. :)

This article has more stuff on .htaccess:
