Hi,
I’m Bogdan and I cannot make a picture gallery with prettyphoto, used by Facts theme, using custom thumbnails.
This is a clasic example that works as expected, but has same picture as thumbnail:

[tds-gallery columns="2"]
<img title="img1" src="1.jpg" alt="info1" />
<img title="img2" src="2.jpg" alt="info2" />
[/tds-gallery]

Here both pictures can be accessed within the gallery (left right arrows visible). I checked with google inspect and there is an automatically added tag named rel=”prettyPhoto[imggallery-1]” to both images.

This is what I’ve tried without success (edit into WP article):

<ul class="tds-gallery">
<li>
	<a href="1.jpg" rel="prettyPhoto[my1]" title="img1">
		<img src="thumb1.jpg" alt="info1" title="img1">
	</a>
</li>
<li>
	<a href="2.jpg" rel="prettyPhoto[my1]" title="img2">
		<img src="thumb2.jpg" alt="info2" title="img2">
	</a>
</li>
</ul>

The thumbnail thumb1.jpg open expected photo 1.jpg but the gallery is not visible (no left right arrows to select the second photo in the gallery).
I believe that Facts theme adds the extra tag data-rel=”prettyPhoto” to all images in the gallery, and this makes prettyphoto to izolate the images.

Here is an example on my page:

I hope you can help me solve this.
Thank you,
