Best dimension for photography portfolio

What ist the best dimension for photography portfolio in Flash?
I would like to make my portfolio website with my photographs.
What dimensions would you recommend?

I would recommend fullscreen, as in, the current size of the browser, so that it keeps changing if/when they resize the browser, making the website expand in a way which fits all resolutions, if you know what I mean (like, when you resize, elements stay in their relative positions when they resize, but according to the resized size)

Thanks, I would like to have nearly the same behavior and design like this site: http://www.sarahcheng-dewinne.com/
Which dimension shall I set for Flash file?

any dimensions, you just need to manipulate the objects using the resize listener, but if you want it exactly like that site, then do change the width and height in the HTML file to 100%, and in the Flash file, add this code to your frame to disable scaling:

Actionscript Code:

Stage.align = "TL";
Stage.scaleMode = "noScale";
