Attaching pictures to a note

Hello, I was searching for a solution to show a base64-encoded image in my note. I used the solution from above, but the image wasn’t shown, only the encoded stuff. So the code number 3 didn’t work in my note.

I found a HTML-based solution like this (image was shown):

<div><img src="data:image/png;base64,/9j/4AAQS...viel Zeugs ...ZRRB//Z"/></div>

I used png- and jpeg-images for my tests.

But I normally don’t want to use HTML-code in my notes.

What can be the reason, that the first code missed?
