Sorry for the confusion, the go code should just give an idea of what I'm doing.  
In the README.md I have the resulting string of the base64-encoding not the go code.

"bog-standard markdown" gives me the search result `https://www.markdownguide.org/basic-syntax/` <https://www.markdownguide.org/basic-syntax/%60>
 which documents the `![alt](link)` syntax?!

Sorry, I'm not getting it.  If someone could point me to a public repository having an image
displayed in a README.md would probably do because usually I'm getting stuff.

Thanks for the effort, Stephan
