 * I hope it’s ok to post PHP specific threads in here. If anyone know of a good
   online forum for a beginning php’er I would be happy to know.
 * Anyway, I want to go through a specific directory and locate all files that ends
   on ‘-thumb.png’ and load them into an array from which I then can select two 
   random images to display independently.
 * Thanks in advance

 * Thanks for your help, I finally figured out how to do it. I struggled with the
   path to the directory, I tried relative paths, absolutes paths but couldn’t figure
   out the right way to do it. In the end I came up with the right thing and the
   following does exactly what I asked in my original question. So if anyone is 
   interested in the same thing, here goes:
 *     ```
       <?php
       $filenames = glob('wp-content/uploads/portfolio/*-thumb.png');
         $rand_files = array_rand($filenames,2);
         $thumb1 = $filenames [$rand_files[0]];
         $thumb2 = $filenames [$rand_files[1]];
       ?>
       ```
   
 * This will put all the files with a ‘-thumb.php’ extension from the portfolio 
   folder, into an array. It will select two random items and put them into two 
   variables. Then I just echo $thumb1 or $thumb2 to display the source of the image.
