You are not closing the tag for <img> in your innerHTML.

Also,

document.getElementsByTagName('html').getAttribute('lang') = "en-US" is an assignment not equality check. Use == instead.

As pointed out by @Akamaozu document.getElementsByTagName() returns HTMLCollection.

document.getElementsByTagName returns an array of elements that match the tag, even if there is only one match.

What you need to do is document.getElementsByTagName('html')[0] to get the first tag returned by the function, which should be your HTML tag.

Also if you want to compare, == or === is what you're looking for. = just sets a value.
