I tested it and that's it, just do a set of images, but put content only on the link of the first. Using example from Lightbox :
<div class="image-set">
<a class="example-image-link" href="img/demopage/image-3.jpg" data-lightbox="example-set" data-title="Click the right half of the image to move forward.">
<img class="example-image" src="img/demopage/thumb-3.jpg" alt=""/>
</a>
<a class="example-image-link" href="img/demopage/image-4.jpg" data-lightbox="example-set" data-title="Or press the right arrow on your keyboard."></a>
<a class="example-image-link" href="img/demopage/image-5.jpg" data-lightbox="example-set" data-title="The next image in the set is preloaded as you're viewing."></a>
<a class="example-image-link" href="img/demopage/image-6.jpg" data-lightbox="example-set" data-title="Click anywhere outside the image or the X to the right to close."></a>
</div>
Simplified:
<div class="image-set">
<a href="img1.jpg" data-lightbox="example-set">GALERIA</a>
<a href="img2.jpg" data-lightbox="example-set"></a>
<a href="img3.jpg" data-lightbox="example-set"></a>
<a href="img4.jpg" data-lightbox="example-set"></a>
</div>
Checking the code of Lightbox, it seems that's it, no there is "create gallery from a single link" . It fetches all href
s and adds to the album of each data-lightbox
. Unless another plugin offers this specific functionality, this is the workaround .
