Image moves outside of the form once phone is held vertically

Also if I hold my phone vertically, the image line to the right goes
over/outside the form.

I think that the code I have mentioned in your other thread will resolve this, but for all others that might experience the same issue, I will post the code again (copy from the other thread):

For that you can use the following CSS code:

img.form-image {
    height: auto;
    max-width: 100%;
}

You can add that code to your form by following the steps here: Inject Custom CSS Codes - just remember to add it after all the other code in there.
