or at least the correct one.
Right now, what's hapenning is this:

imagine you have this layout:
/
/product_images/
/product_images/dir1/
/product_images/file1.ext

What your script is doing:
$handle = opendir($path);
while (false !== ($file = readdir($handle)))
{
// $file = '.' // on first run
// $file = '..' // on 2nd run
// $file = 'dir1' // on 3rd run
// $file = 'file1.ext' // on 4th run

if ($file != "." && $file != "..")
{
echo $file;
if (is_dir($file)) // it's not, since that file doesn't
exist in the place PHP is looking for it.
// because, does ./dir1/ exist? no! does ./product_images/dir1/
exist? yes!
// But that's not what you're checking ;)
{
echo ' <-- folder<br>';
$folders[] = $file;
}
elseif (is_file($file))
// same thing as with is_dir()
{
echo ' <-- image<br>';
$images[] = $file;
}
else
{
echo ' <-- ???<br>';
}
}
}
