This post is also exactly my question:
When I make my screen small (like on computer, ipad, cell phone), the next and previous arrows show up and the black transparent background with picture info too. But when the screen is normal size they dont show up.
Like this it only displays one pic and I wonder if people realize it is a gallery like that.
Other than that, I love this plugin!
You say this is how it was intended, but is there anyway to have the arrows and the black transparent picture info show up at any size of the screen/permanently? I tried to look into the code, but I am not that good at that... I love this plugin though, it looks so clean and works great on smaller screen, just would really like it the same on larger screen.
