Instead of outputting every file name, store file names in an array
(lets say, $files) and then randomly draw five elements from that
array:
$n = count($files) - 1;
for ($i=1; $i <= 5; $i++) {
echo 'fadeimages[', $i, ']=["images/', $files[rand(0, $n)] ,'", "",
""]';
}
For more information on rand(), see the Manual:
