Figured out #1. This jqeury adds the “first_thumb” class to the hovered element.
<script>
jQuery(document).ready(function($) {
jQuery(“.avia-gallery-thumb a”).hover(function(){
jQuery(‘.avia-gallery-thumb a.first_thumb’).not(this).removeClass(‘first_thumb’);
jQuery(this).addClass(‘first_thumb’);
})
});
</script>
