Photohabit,
Although I have different sized photos, here is the HTML code I use, placed in the 'description' box of the gallery. Perhaps you can adjust this to get the desired results your looking for. I can't help you any further than this though, as I only got some info off an HTML tutorial site and messed with it to give me what I wanted. Some of my coding may even be incorrect but it's working the way I want. CSS codes are beyond me so I'm stuck in HTML land and perhaps this will help someone in a similar situation.
I see you have various sized photos so this may not be of much help to you, as Arielen suggested.
