You mustn’t use quotation marks around the name of the image files in markdown!
If you carefully read your error message, you will see the two %22
parts in the link. That is the html encoded quotation mark.
You have to change the line
!How to embed image or picture in jupyter notebook, either from a local machine or from a web resource?("img/picture.png")
to
!How to embed image or picture in jupyter notebook, either from a local machine or from a web resource?(img/picture.png)
UPDATE
It is assumed, that you have the following file structure and that you run the jupyter notebook
command in the directory where the file example.ipynb
(<– contains the markdown for the image) is stored:
/
+-- example.ipynb
+-- img
+-- picture.png
