Tried the Meta Slider lightbox with a number of the indicated lightbox plugins, but with none of them will titles be displayed on the lightbox slideshow.

Captions are displayed on the Meta Slider. I even have one image where the title, caption, alt text and description are all filled in. This will however still show noting. In the source code I can see that the alt tag remains empty.

Tried it with the following lightbox plugins:

• Easy FancyBox
• Responsive Lightbox by dFactory
• WP Lightbox 2 (which is not working at all)
