Notice how you turned the words “cat photos” into a link by wrapping it with the appropriate a tags. That’s how you turn anything into a link. So you’ll want to do that for the img tag.
I don’t know what this means? You’ll need to show me your updated code so I can see what you are doing.
To display your code in here you need to wrap it in triple back ticks. On a line by itself type three back ticks. Then on the first line below the three back ticks paste in your code. Then below your code on a new line type three more back ticks. The back tick on my keyboard is in the upper left just above the Tab key and below the Esc key. You may also be able to use Ctrl+e to automatically give you the triple back ticks while you are typing in the this editor and the cursor is on a line by itself.
Look at what you did to turn “cat photos” into a link. You wrapped it in the appropriate a tags. Have you done that for the img tag? I think you are missing something at the end.
