Django extends is not extending anything

I am trying to use the extends tag to extend code from my base.html to the other files. At first it was working great. I moved on to my home page and made an image folder and tried transferring an image into the folder. now when I load the page none of the base.html will transfer. and I see a ? on the page with the images folder.

Note: When posting code, error messages, templates, etc, copy / paste the text of the code into the body of your post, surrounded by lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. Please do not post images of code here.

thank you for pointing this out to me. I apologize for my mistake.

As for the solution, it seems that I had been extending code but it did not follow the HTML guidelines necessary.

Like when you type out ! and than hit

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

I think I needed a head element and other required elements.
