change picture on mobile device

If you go to my website https://workwithbrybry.com/blog
you’ll see at the top, I’ve added a header
image below the logo.

Is it possible change it to a different image ONLY when
viewing on a mobile device? So far, I know that if I add
a code like this

<?php
if ( wp_is_mobile() ) {
	/* Display and echo mobile specific stuff here */
}
?>

then maybe it’ll get me somewhere
