Hi there.
Also looking for a way to have image descriptions visible.
The only solution I have found so far is using the optional attribute title= “insert text here” but this solution is not elegant. It would be really neat if the actual img title, caption and descriptions as given under media settings could be toggled on / attributed easily to the lightbox image view.
I’m working on custom css atm (as the title attribute position is all messed up) and will get back if the solution is any good.
