     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.

// ——————— END CONFIGURATION ———————–
