Hello Angelo,
Thank you for your quick answer.
I mean a classic visible caption that can be one with the image. It currently exists in the gallery, but not in the image. I'm making 10 books with more than one hundred images each and doing the captions by adding a rectangle and a text box is Carthusian monk work. Plus every action: disappear, appear, must be programmed three times.
I will write to support, where can I find information about the development package? Interesting.
