Styled images not working as expected

[raphink]

Styled images as implemented in #411 do not work in 0.19.6. Instead, they produce:

<img src="image/_images/rad_image.png" alt=".right Some rad image">

Hmm. I cannot reproduce. Did you also say this was with a Docker container?

Yes, that is using a Docker container iirc.
