How to remove the image title/caption from your thumbnails
If you want to remove the image title/ captions from your thumbnails the easiest way to do it is to go to Modula > edit gallery > Captions > Turn ON 'Hide title' and 'Hide captions'.
You can see in this image that the title and the captions are shown.
In the image below the title and captions are not displayed because the options to hide them were enabled.
You can also hide them if you use the None hover effect.
