Looking for a code that will load a different image randomly on each refresh. I've seen it before but cant find it. Thanks

Can you be more specific? You talking about an avatar or what?

Code:




<?php 








if ($dir = opendir(".")) 





{ 





     $list = buildimagearray($dir); 





     displayrandomimage($list); 





} 











// This function reads all the files in the current directory and adds all image files to the array $list[] 











function buildimagearray($dir) 





{ 





     while (false !== ($file = readdir($dir))) 





     { 





          if (!is_dir($file) && getimagesize($file)) 





          { 





               $list[] = $file; 





          } 





     } 





     return $list; 





} 











// This function selects a random image, determines the mime type, opens the file for reading, 





// and then outputs the image 











function displayrandomimage($list) 





{ 





     srand ((double) microtime() * 10000000); 





     $sig = array_rand ($list); 











     $size = getimagesize ($list[$sig]); 





     $fp = fopen($list[$sig], "rb"); 











     if ($size && $fp) 





     { 





          header("Content-type: {$size['mime']}"); 





          fpassthru($fp); 





          exit; 





     } 





} 





?>

try it, it works on mine, just put the images files you want in that same directory that this file is in. Then try image code pointing to that file.
