Changing image size in Markdown

Question

I just got started with Markdown. I love it, but there is one thing bugging me: How can I change the size of an image using Markdown?

The documentation only gives the following suggestion for an image:

![drawing](drawing.jpg) 

If it is possible I would like the picture to also be centered. I am asking for general Markdown, not just how GitHub does it.

Answer 1

With certain Markdown implementations (including Mou and Marked 2 (only macOS)) you can append =WIDTHxHEIGHT after the URL of the graphic file to resize the image. Do not forget the space before the =.

![](./pic/pic1_50.png =100x20) 

You can skip the HEIGHT

![](./pic/pic1s.png =250x) 

And Width

![](./pic/pic1s.png =x250) 

Answer 2

You could just use some HTML in your Markdown:

<img src="drawing.jpg" alt="drawing" width="200"/> 

Or via style attribute (not supported by GitHub)

<img src="drawing.jpg" alt="drawing" style="width:200px;"/> 

Or you could use a custom CSS file as described in this answer on Markdown and image alignment

![drawing](drawing.jpg) 

CSS in another file:

img[alt=drawing] { width: 200px; }
