Markdown only two basic layout modes: inline & block. Before we think about applying others with an attribute or a shortcode, we need to understand them.
Markdown has become the favored markup language to structure text files. With good cause: The syntax is intuitive and there are a lot of possibilities to translate them into a visual layout format.
Perplex handles all Markdown images by default as floats inside a text block. Self-contained separate images are the domain of the figure shortcode. But there is a fallback for the widespread self-contained use of Markdown images.
