I'm trying to create a block of php that displays random images. so far i have:
<?php
                        echo rand(   );
            ?>


Now i found out that you can only have integers in the rand( ) function, so is there another peice of code i need to put URl's in the function?

That rand function is used more or less with a query. Is this image information stored in a database?

I did a search on the net about it and found a code that works, with this code im storing the images in an array, from outside sources...such as URL's. But yea, i did find a working code.

Just a quick FYI


   $bg = 1;
   $bg_dir    = 'PATH_TO_IMAGES';
   $bg_count    = opendir($bg_dir);      
      while ($file = readdir($bg_count))
         {         
         if (($file != ".") && ($file != "..") && ($file != "index.htm"))
            {
               $bg++;   
            }   
         }
         
   $random_bkg = rand ( 1, $bg );

   $bg_dir_c    = 'PATH_TO_IMAGES';
   $bg_file_c   = opendir($bg_dir);   
      while ($file2 = readdir($bg_file_c))
         {         
         $new_file    = explode(".", $file2);
         $check_file = $new_file[0];   
         }


Something like that would have got you a random image, $check_file being the filename...
