Need ideas to solve my photo browsing problem on my site

Click on “galleries” then click on “Families”.

My problem is that if picture is too big the animation goes off the edge of the swf and gets cut off. But if I make picture small enough so animation doesnt get cut by border of swf than there is a lot of empty space and pics not as easy to see.

Any ideas how I can accomplish this by keeping pics a good size? Right now the site is made for low resolution monitors so that everyone cna see it without haveing to scroll. Is my only solution make swf wider/taller and not supporting the lower resolutions?

What is a good resolutoin standard to support these days?
