You might look into using a flash photo gallery or JQuery with the photo stacking options. Not sure, but JAlbum may have a skin for their free software that does that effect.
The other way is the hard fixed, way. Using the CSS position property along with the z-index set for each image. Then you can stack them as you wish.
