I've reached out to NextGen with questions about their slideshow with no response. So i turn to you fine folks.
1. How do you add captions to the slideshow?
I tried in the description field under the alt text, but it didn't appear.
See this link for a screen grab of what I tried.
2.The horizontal photos look great, but the vertical pics are aligning left. Is there a way to get them to center?
This link has a picture of what's happening
3. Is there a way to change the speed of the transition between photos during the slideshow? I'd like it to go faster.
