Question about single image

I fixed it ??

for others:

When you are using a single image create a custom template for that page, then add the shortcode from the slider in a div:

Example:

<div class="werkwijzeslider">
<?php do_action('slideshow_deploy', '400'); ?>
</div>

then in your css :

.werkwijzeslider .slideshow_container_slideshow-jquery-image-gallery-custom-styles_1 .slideshow_previous { display:none!important;}
.werkwijzeslider .slideshow_container_slideshow-jquery-image-gallery-custom-styles_1 .slideshow_next {display:none!important;}
