How do you do this...

I see this is used a lot (the below mirror effect).

I discovered it when playing arround with iweb - after finding dreamweaver a little slow I wanted to see what iweb was like.

When you add in an image within iweb, on certain pages it drops this effect in. Yet I cant seem to do it manually - what's it called and how can I do it manually to other images?

 

Ok so I've found it as a submenu called reflection.

Cheers all the same.
