How would I get the "raw" html for image block?

When getting the html via `editor.getHtml()` the code has `<imageblock/>` tags and therefore can't be rendered using just regular HTML. How would I get the "raw" html where these `<imageblock/>` tags are `<img/>` tags?

My use case is that I want to export blogs created with Dante to other websites like Wordpress.

Thanks in advance for any info.
