Answer 1

Try like this:

<marquee behavior="scroll" direction="down" bgcolor="#">
    <img src="https://habrastorage.org/files/424/8f3/201/4248f32017604e4daecb7bb95a343bb1.jpg" alt="4248f32017604e4daecb7bb95a343bb1.jpg">
  </marquee>

To make the images move from bottom to top, replace direction="down" with direction="up".
