It's not confidental, but I don't want users figuring out my backend image
code from it. While I'm not sure what they could do with it other than make
images the way they want and display then for themselves I don't see any
danger in it. I just don't like messy long URL lines. I'm already going to
be giving the users a way to customize the site so they don't need to me
messing with varibles passed to the image script. As for your comment about
the back button I have come up with a section of code for my site that stops
user for doing much with the back or reload button. I keep track of a link
counter in a session var and then if they hit back or reload the link
counter that gets sent in the post data is not equal to counter++ and so I
redirect them to an error page that explains that the site does not allow
the use of the back button or reload buttons.
