How about a line or two under each of the large pictures? OTOH, most people looking at them may know what they are all about.
Site loads fine and fast on cable! Might want to watch what gets into each picture. If you've got a digital, you should be able to see it afterwards, especially when using a flash, objects that are close will be too bright. That view of the shower/bathroom really doesn't need the towel showing!
