Hello David,
yes, it can be done. See how we are doing this with our TYPO3 theme:
Here is what I figured out:
Image float left ================ .. |example-teaser-left| image:: ../images/loremipsum/a4.jpg :alt: Left floating image :class: float-left with-shadow |example-teaser-left| Typesetting is the composition of text by means of arranging physical types[1] or the digital equivalents. Stored letters and other symbols (called sorts in mechanical systems and glyphs in digital systems) are retrieved and ordered according to a language's orthography for visual display. .. rst-class:: clear-both Floating cleared. Below the image.
You may have to add the classes '.clear-both {clear: both}' and '.float-left {float: left ! important}' to the CSS of your theme.
