Our premium themes comes with built-in Lightbox which allow you to display images in dialog boxes.
We have updated our Lightbox JavaScript files to display captions (screenshot above). Here is a guide how it can be done:
1. Login to your Admin Panel, navigate to Left Menu -> Appearance -> Customize -> ‘Lightbox’ section and make sure the options for display of Lightbox are Checked.
2. Open a Page or Post for edit in Admin Panel
3. Insert an image with ‘Link to Media file’ option set
3. Edit the image as HTML
5. At the and of <a > tag, inset data-title=”Your Caption TEXT”, i.e.
<figure class="wp-block-image"><a href="https://example.com/wp-content/uploads/2019/01/Papageitaucher_Fratercula_arctica.jpg" data-title="Lorem ipsum dolor sit amet, primis platonem dignissim"><img src="https://tishonator.com/dev/wp-content/uploads/2019/01/Papageitaucher_Fratercula_arctica-1024x683.jpg" alt="" class="wp-image-419"></a></figure>
