Error shown saying that image should have src, even after adding src to the image, but don't know where I went wrong

Your link is still wrong.

Two issues.
No.1: This is not how you spell curriculum

No.2: img tags do not have closing tags.
This is incorrect

You need to use the correct cdn link with everything spelled correctly for the tests to pass.

Hope that helps!

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
