   ABOUT
   This PHP script will randomly select an image file from a
   folder of images on your webserver.  You can then link to it
   as you would any standard image file and you'll see a random
   image each time you reload.
   
   When you want to add or remove images from the rotation-pool,
   just add or remove them from the image rotation folder.


   VERSION CHANGES
   Version 1.0
      - Release version
   
   Version 1.5
      - Tweaked a few boring bugs
   
   Version 2.0
      - Complete rewrite from the ground-up
      - Made it clearer where to make modifications
      - Made it easier to specify/change the rotation-folder
      - Made it easier to specify/change supported image types
      - Wrote better instructions and info (you're them reading now)
      - Significant speed improvements
      - More error checking
      - Cleaner code (albeit more PHP-specific)
      - Better/faster random number generation and file-type parsing
      - Added a feature where the image to display can be specified
      - Added a cool feature where, if an error occurs (such as no
        images being found in the specified folder) *and* you're
        lucky enough to have the GD libraries compiled into PHP on
        your webserver, we generate a replacement "error image" on
        the fly.
      
    Version 2.1
        - Updated a potential security flaw when value-matching
          filenames

    Version 2.2
        - Updated a few more potential security issues
        - Optimized the code a bit.
        - Expanded the doc for adding new mime/image types.

        Thanks to faithful ALA reader Justin Greer for
        lots of good tips and solid code contribution!


   INSTRUCTIONS
   1. Modify the $folder setting in the configuration section below.
   2. Add image types if needed (most users can ignore that part).
   3. Upload this file (rotate.php) to your webserver.  I recommend
      uploading it to the same folder as your images.
   4. Link to the file as you would any normal image file, like this:

         <img src="http://example.com/rotate.php">

   5. You can also specify the image to display like this:

         <img src="http://example.com/rotate.php?img=gorilla.jpg">
      
      This would specify that an image named "gorilla.jpg" located
      in the image-rotation folder should be displayed.
   
   That's it, you're done.

*/




/* ------------------------- CONFIGURATION -----------------------


   Set $folder to the full path to the location of your images.
   For example: $folder = '/user/me/example.com/images/';
   If the rotate.php file will be in the same folder as your
   images then you should leave it set to $folder = '.';

*/


   $folder = '.';


/*   

   Most users can safely ignore this part.  If you're a programmer,
   keep reading, if not, you're done.  Go get some coffee.

    If you'd like to enable additional image types other than
   gif, jpg, and png, add a duplicate line to the section below
   for the new image type.
   
   Add the new file-type, single-quoted, inside brackets.
   
   Add the mime-type to be sent to the browser, also single-quoted,
   after the equal sign.
   
   For example:
   
   PDF Files:

      $extList['pdf'] = 'application/pdf';
   
    CSS Files:

        $extList['css'] = 'text/css';

    You can even serve up random HTML files:

       $extList['html'] = 'text/html';
       $extList['htm'] = 'text/html';

    Just be sure your mime-type definition is correct!

*/

    $extList = array();
   $extList['gif'] = 'image/gif';
   $extList['jpg'] = 'image/jpeg';
   $extList['jpeg'] = 'image/jpeg';
   $extList['png'] = 'image/png';
   

// You don't need to edit anything after this point.
