Please include image sizes, as in discount_markdown

[ghost]

Discount Markdown, includes very nice image sizes. http://www.pell.portland.or.us/~orc/Code/discount/ and such contribute to HTML validation. Please look at the link for the example. I need to use hoedown because there is Guile extension to it: https://github.com/greghull/sundown-guile

Image sizes in HTML are required. This can be easy option to implement.

Also, could some aligning of images be added?

It would be nice to support pandocʻs image attributes, like {#id .class width=30 height=20px}.

This is affecting our use of MacDown which employs hoedown for its rendering.

We have hundreds of Markdown documents using the =[n]x[n] syntax and currently the parser just ignores them.

Any news of progress on this?
