asciidoctor: WARNING: image to embed not found or not readable: /tmp/images/

Hi
I have a issue with relative path in asciidoc (like in image:./images/photo.jpg) and the only way to solve is adding dir="./" in blogger.py:
```
                with self.namedTemporaryFile(delete=False, dir="./",
                                             suffix=".adoc") as fp:
```
and now relative path work to me.
