correction
They css code I added was:
.yarpp-thumbnails-horizontal .yarpp-thumbnail, .yarpp-thumbnail-default, .yarpp-thumbnail-title {display: block !important;}
.yarpp-thumbnails-horizontal .yarpp-thumbnail, .yarpp-thumbnail-default {display: inline-block !important;}
.yarpp-thumbnails-horizontal .yarpp-thumbnail {
border: 0px !important;
width: 0px !important;
height: 0px !important;}
