Embedding screenshots

What I want to achieve: I want to embed screenshots. I do not want them to big in the document otherwise it distracts readers.
I need a button below the small embedded screenshot, once clicked a new window opens with a readable screenshot.
I implemented this with this HTML snippet

<a href="Passwort_erzeugen.png" target="_blank">
 <img src="Passwort_erzeugen.png" alt="Passwort Erstellung" width="300">
</a>

This working fine, but implements a broken icon because of security concerns - I learned.

Now I guess my question is: Is it possible to implement above functionality with markdown syntax?

If you use plain HTML I think you have to use the actual full path to the file, which should be /.fs/Passwort_erzeugen.png

Alternatively the transclusion syntax has support for resizing Transclusions

Full path in HTML does not help. It actually shows a downsized version of the screenshot. Transclusions is right now way over my pay grade. Thank you.

I don't want to make any assumptions on your pay grade, but the word transclusions is more complicated than the implementation:

![[Passwort_erzeugen.png|300]]

It even gives you a nice "Eye-con" to click on for the zoomed in view. You can also wrap it in an html link if you like.
