问题
I am trying to insert an image in Google Colaboratory (markdown) already saved in Google Drive using this expression  but it doesn't work. For example, the Colaboratory markdown manual shows how to insert a photo inline with this example An inline image: . Ok, that is a photo from internet, but, when I replace that photo for one already saved in my Google Drive it doesn't appear.

I tried all the answers above and nothing worked because of a small change Google has created recently(at the time of writing this post). If you click on "Get Shareable link" and paste it, it would look something like this:
https://drive.google.com/open?id=12BumFEqzKxc9mog8tYuUqvpxf10ot6W3
Now just change the open?id to uc?id and it will instantly work.

Unfortunately, I have tried the methods above but they didn't work for me. Then I have tried simply right-clicking on the picture that I want to display on colab, and choose 'Get a sharable link', then the link is automatically copied to my clipboard:
The link will be something like
https://docs.google.com/uc?id=-----
Then using colab's picture inserting button, and insert that link to the (https://) part
worked like a magic!
However, if you get a link like this
https://drive.google.com/file/d/-------/view?usp=sharing
after making picture public, it somehow doesn't work.

From the next 3 formats only the first one worked for me:

Here is an example using plain html instead of markdown.
<figure>
<center>
<img src='https://drive.google.com/uc?id=1Rb6oXW3KufLApvID5MwxsknpoON2CkQ_' />
<figcaption>Image Caption</figcaption></center>
</figure>
This way, you can also center the image, add captions etc
