Unwanted image title

I have activated Shadowbox-js version 3.038.
When I view an image in the shadowbox I get the image file name at the top but I don’t want the file name to show.

When I downloaded the Shadowbox-js .zip file, it automatically downloaded two versions, including the one that includes the file name. I only activated the basic shadowbox but I get the filename anyways.
Can anyone help me stop showing the filename?
Thanks,
