Images Gallery Element - Caption - Where do you enter it?

When you use the images Gallery Element there are 3 options to enter against each image, Caption, Title and Description.
I can see where to enter Title and Description., but I can't see where you enter the Caption?
Where to I enter the Caption information

Hi
in "images gallery edition", you can select the image, the title and you can write a text/content in the editor : this is the caption

Hi Cedric,
I am now a bit confused??
in the editor section, I thought that was the 'Description' ???
If the editor area is the 'Caption' where is the Description??

my fault
here is the answer : the caption is TITLE + DESCRIPTION
if you hide the caption, you will hide both, it is the container of both items

Thanks Cedric.... David
