$image_file = 'foo.jpg'; $random = mt_rand(1, 2000000000); $url = "http://example.com/program/$random/$image_file";; echo "<img src=\"$url\"> In program, if you echo out $_SERVER['PATHINFO'] you will see: /454398574395/foo.jpg The number will change, of course. You can tear that apart and get the foo.jpg part to do whatever you want. Or, you could have the URL sometimes have 'copyright' in it, and sometimes not, and merge only when the URL has copyright in it. You could even pass is paraeters like this: http://example.com/program/width=200/2343242343/foo.jpg Take the width=200 and scale the image to be 200 pixels wide. Here is a real live example where I do this: http://uncommonground.com/artist_profile/Ellen+Rosner Right-click on that image of Ellen in the chair and check out that URL. thumbnail is my PHP script. target is a max width/height (I scale it proporationally and 200 is max for both) credits is the photographer credits from my database. The rest is the URL of the actual real image I'm dinking with. Feel free to play with the URL and change the 200 to, say, 100, or make believe YOU took that photograph. All just from the URL which, as far as the browser can tell, is a perfectly valid set of directory paths on my machine, so the browser can't possibly screw up. (Rule #1: Never trust the browser.) And in the main link, artist_profile is the PHP script, and if you look at the links to the other artists at the bottom of the page, you'll see that it also uses PATH_INFO to either show an artist by ID or to search for their name in our database. If multiple matches are found, the user is asked which one they meant: http://uncommonground.com/artist_profile/Ellen If I have the ID, then I know exactly which one to display. I actually would suggest you go with: /width=200/ though, instead of /width/200/ as it's easier to code and have optional parameters using = and / as an arg separator. I haven't bothered to fix that old script, but that's how I do it nowadays.
