Link image to full size image in markdown
This is the markup for adding image in Markdown:
![Alt text here](/images/foo.png)
To make clicking on image open a bigger version of the same image, do this:
[![Alt text here](/images/foo.png)](/images/foo-big.png)
I figured this out intuitively before finding out it’s right there in the docs and probably common knowledge to most Markdown users but I didn’t use it until recently.
