        if ($ext) {
            $ext = strtolower($ext);
        }

        $imageUrl = $this->getBaseUrl() . $this->getPath();
        $imageData = base64_encode(file_get_contents($imageUrl));

        switch ($ext) {
            case "jpeg":
                return 'data: image/jpeg;base64,'.$imageData;
            case "jpg":
                return 'data: image/jpg;base64,'.$imageData;
