Can I change the image slideshow to thumbnails?

Hello,

Yes, If you’re a developer you should override property show and listing gallery activity in your theme, then you can apply desired changes in overridden files.

Please check this KB article.

If you have no knowledge about PHP and WordPress coding, we can provide you a quote for doing this customization. Please open a ticket here.

Create a new listing_gallery in pshow_position2 under Activities. Then disable the existing pshow listing_gallery

thank you, match858. It works.
But now, after I disabled the existing pshow listing_gallery the Google map would not load at first, need to click on it

Are you able to access the files on your server? If so you should follow the steps outlined here for changing the template https://support.realtyna.com/index.php?/Default/Knowledgebase/Article/View/549/28/developers—-how-to-override-wpl-views-on-a-theme

Then add this script to the top of the new property show default template
<script type=”text/javascript”>
wplj(document).ready(function()
{
wpl_pshow_map_init();
});
</script>
