How to resize github images inside github flavored markdown (i.e. issues / PRs)?

Is there any quick and easy way to change the size of an image pasted into a github issue?

Example

Here's a random github image. If it's used in a github issue like so

![image](https://user-images.githubusercontent.com/16319829/79087218-ef769280-7d81-11ea-93d6-a81ea2a7474e.png)

It will display largish.

How can we easily make it medium or small as simply as possible (preferably by only editing the url or adding something to it)?

What I've tried

I tried both of these (suggested here), but neither work:

Note

• I'm not sure how it works, but stack overflow have a very convenient convention of adding an l (large), s (small), m (medium) to end of an image url to change the size (I also tried this in github but no luck)
