How do I remove date and size below text and images ?

Hi,

I installed Gallery2 on my server.

My question is: how do I remove the Date and Size below text and images?

Look here what I mean: http://80.197.126.74/Gallery/main.php
Marked with red circle: http://peecee.dk/uploads/082009/Untitled10.jpg

I have the same theme as this user: http://www2.ramoth.org/gallery/main.php

And as you can see, he has removed Date and Size I have visited several users who use Gallery2, and they have also removed the date and size.

I spent several hours, but I can not figure out how to remove it, I've tried to write mails to several of these users, but has received no answer yet ...

Hope there is someone here on this forum who can help me.

Excuse my bad English but I come from Denmark.

Regards
Sune
