I’m using Markdown more and more on my Blog, thanks to @Jannis 's Poster. It is working really well, except I was struggling to centre images and define size.
This is working as a fix:
To center images, text, and anything else in Github markdown and READMEs simply wrap the element in an HTML tag with the align attribute set to "center" .
Image is size defined and centred, but it is html, which I have always tried to avoid!
Is there a ‘proper’ Markdown way of doing this? I can’t find it on Github, IA Writer notes or others - perhaps it is beyond John Gruber’s spec for MD?
