try the absolute path in is_dir and is_file 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>';
