Choosing Featured Image as source for single image

Hi there,

after reading the Visual Composer Documentation, I discovered that there should be an option to choose the source for a single image block (Visual Composer), e.g. to display the featured image within this content block. But it is not! 🙁

So, I’ve created a support ticket at the Visual Composer Support and they answered, that the Theme Designer (you) has removed / disabled this option for the Single Image block (vc_remove_param).

Can you tell me how to enable this nice feature / option?

Thx in advance.
Nick
