How To Remove Captions From Slider Images

Hello,
Does anyone know how to remove all captions and the caption boxes from the slider images? If I leave them blank, default copy appears, and if I just put spaces in there, I still get the box over my images. I just want images, no caption boxes. Thanks.

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

#slides .caption{
display:none;
}
