Logo overlay on full screen slider

well you can use your full-screen slider aswell and add your logo via jQuery function.

Here on my testpage i have given the slider the custom-class: place-logo

then i put into functions.php of my child-theme:

Test-page: https://webers-testseite.de/cynthia/logo-goes-to-slider/

function add_logo_to_slider() { 
?>
<script>
(function($){
	$('.place-logo .slideshow_caption').before('<img class="sliderlogo" src="https://webers-testseite.de/cynthia/wp-content/uploads/2018/07/full-logo.png" alt="Logo on Slider" />');
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'add_logo_to_slider');

and make a setup for your added image for each slide number like:

/* rule for all slides in the slider */
.sliderlogo {
position: relative !important;
width: 40% !important;
top: 35%;
transform: translateY(-50%);
-webkit-filter: drop-shadow(2px 2px 3px #ffffff);
filter: drop-shadow(2px 2px 3px #ffffff);
}

/* if you like to have semitransparent background with padding for slide 1 */
.slide-1 .sliderlogo {
    background-color: rgba(255,255,255,0.2);
    padding: 40px;
}

/* if you like to shift in x direction for slide 2 */
.slide-2 .sliderlogo {
	margin-left: 10% !important;
}
