Sorry if I jump in late in this thread, but wouldn't this work?
<code>
$file = "images.txt";
$openFile = file($file);
$num_images = 10;
# don't need this is PHP > 4.2.0
srand((float) microtime() * 10000000);
$random_keys = array_rand($openFile, $num_images);
foreach ($random_keys as $random_key) {
echo "<img src='$random_image' height='170' width='100'></img>";
}
</code>
array_rand: http://php.net/array_rand
Maybe I'm missing something... Anyway, cheers everybody!
