Adding images in markdown
To add images in markdown we use a similar syntax to the one used for links ie. text in square brackets and a link to the image in round brackets, with an extra exclamation mark added before that:
![alt text](image_url)
This way what we write in the square brackets will function as an alt text in case the image does not load. We can also add a tooltip when hovering over the image
![alt text](image_url 'tooltip')
![A cute dog](https://picsum.photos/id/237/200/300 'A cute dog')
which will look like this:
