The error comes like this
Oops, try again.
Make sure at least one of your images is also a link!
if you edit/update your question, leave a reply so i get a notification. Your code is not visible, take the following steps to make your code visible:
select your code and press ctrl + k (or cmd + k if you use a mac)
if this instructions are unclear, you can also insert 3 backticks before and after your code, like so:
``` <p>visible</p> ```
the backtick is located above the tab key on your keyboard
It means your image should be a link. Like this:
<a href="#"><img src="link-to-image" /></a>
Try to remove the '/' at the end of your img. Img is a self-closing tag.
<a href="#"><img src="link-to-image"></a>
