Hi Tobias
http://tiddlywiki.com/#UsingSVG
TiddlyWiki supports using SVG images in two ways: self-contained tiddlers
of type image/svg+xml, or wikitext tiddlers containing inline SVG elements.
The advantage of the latter is that it is possible to style the image
elements with CSS.

item. That, I have still not managed to achieve, e.g. defining the field

Have you tried <$image source={{!!img}}/>?
Best wishes
