You can add text, image, video or any HTML to the lightbox gallery.
Go to the product edit screen and find the Product Image box:
Once you click the Add HTML button on the lightbox gallery edit box you will see a popup with text editor:
In this popup you can add any content. For example you can:
- Add a YouTube link – it will automatically generate a video iframe
- Add any text that will show up in the slider
- Add HTML to create buttons or any other content
- Add images or other media from your WordPress media gallery
This HTML content will show the same as any other product lightbox element. Once clicked it will get bigger as any other image added to the lightbox gallery.
