Markdown: smaller images sizes not supported by GitHub?

Question

I want to downsize some of my images in my README.md on GitHub and it works fine in my Markdown editor using something like

![](./images/my_img.png =400x)

However, when I upload it to GitHub, the Markdown viewer seems to not like it. Any suggestions or ideas how I can downsize the images without reducing the resolution of the images themselves?

Answer 1

Github doesn't apply the style attribute but obeys the width and height. So for github you can use the following HTML tag directly in the markdown:

<img src="url" alt="alt text" width="whatever" height="whatever">
