Insert Text Above Archive Title

How would I insert text above the Archive Title? I want to add a phrase or an image above the category title. I tried this, but I don't know what I'm doing.

add_filter( 'get_the_archive_title', 'mj_insert_text_above_title' );
function mj_insert_text_above_title( $title ) {
if ( is_post_type_archive() ) {
echo 'The Categories';
}
}
