How to add text over Slideshow/carousel?
First of all you are using views + views slideshow for the slideshow, correct??
And you are using a slideshow content type. 

No => use views + views slideshow to show your slideshow contents as a slideshow. You can find instructions in its documentation and many videos to help you out(google knows best!! :))

Yes =>


in views : should show fields and not content
so you will have 2(or more per your need) fields : image and text(custom text area or say your title)
Using css you can position your text.


Hope it helps....keep posting your problems in comments...the community will always help you out.
