How to center small image in center of screen.

[saw15]

I am trying to center a small image in the middle of page regardless of screen resolution.

In short, we are using a company logo and a english and spanish button below it.

I handle the left & right centering with a :
<div align="center">

But how do I handle the top and bottom centering? I know I can add <br> etc, but if the screen resolution changes it won't stay centered.

Sorry to be so simple, but never really had to do this before.

Help is appreciated.

Disregard, i got it using align and valign in the <td>.
