Tiled Gallery

I was wondering if there was a way to choose how images appear in the tiled mosaic setting? Can I choose which ones are placed next to each other and what size they will be? Say I have four pictures, one is a wide angle shot, and the other three are of individual people in the shot and I want them side by side, to be one on top and three on the bottom. Is there a plug-in or options I can select to change this? Thanks for your help!
