Hey Mitchoo –
I need to do the same thing – my customer wants the photos to display first but have their YouTube videos display last in the slider. So I modified (in a child theme) templates\listingslider.php and moved the video section (around line 47) after the photo section. Basically just reversed the order so the photos come first. I also had to remove the class name “active” from the line (now at line 97) that begins “$indicators.='<li data-target=”#carousel-listing”…… and also from the line (now at line 101) “$slides .= ‘<div class=”item ‘.$videoitem.'”>’;”.
It would be great if this were something we could control from the theme options, though.
Hope that is helpful.
