Cant upload a photo from my images folder to notepad++ (works only with image address from net)

[Ofek Biton]

Started learning HTML & CSS not a long ago, And I cant upload photo via my images folder.
Works well through net ( with image address), but doesn’t with the folder.
What the problem could be?

Code:
Via net:
<img src=“https://upload.wikimedia.org/wikipedia/en/8/83/Atletico_Madrid_logo_new.png” />

Via folder:
<img src=“images/ATM.jpg” />

Thank alot !
