Latest release of Novelang available here.
This version introduces support for raster and vector images.
The source document references them through a path which can be either relative (from the document itself) or absolute (from the project root).
And, yes, images may show inside table cells! Otherwise they must appear outside of paragraphs. Suported formats are
.svg. SVG may or may not be rendered in HTML pages, depending on Web browser capability.
See documentation for details.
