Does not show image by url

Hi in thumbnail.php around line 100 in fifu_replace() which is a filter for post_thumbnail_html we have:

    if ($url) {
        if (fifu_is_on('fifu_class')) {
            if (strpos($html, 'class='))
                $html = preg_replace('/class=[\'\"][^[\'\"]*[\'\"]/', 'class="fifu-class"', $html);
            else
                $html = str_replace('<img', '<img class="fifu-class"', $html);
        }

        return $css ? str_replace('/>', ' style="' . $css . '"/>', $html) : $html;
    }

    return !$url ? $html : fifu_get_html($url, $alt, $width, $height);
}

I added some logging.
If there is a $url (it exists in my case) it returns prematurely in the line ‘return $css ?….’ without having the chance to add the image.

This is done in the last line but it never gets there if $url exists.

I think a proper patch is:
