It seems like you do not handle an error condition for iptcembed(). This can introduce security issues, and is generally not recommended.

        $info = null;
        getimagesize($file->getPathname(), $info);

        if (isset($info['APP13'])) {
            $this->data = iptcparse($info['APP13']);

It seems like iptcparse($info['APP13']) can also be of type false. However, the property $data is declared as type array. Maybe add an additional type check?
