Try this bit of code and see if it works. (I don't know if there's a less
taxing (on the server) way to get a count of files in a directory or not.)
$myDirectory = dir("yourdirectory");
while($entry=$myDirectory->read())
{
$filecount++;
}
$myDirectory->close();
$number = rand(1, $filecount);
$file = $number . "." . "gif";
echo"<img src = 'random_images/$file'>";
