Hey Aura, Here is what one can easily do with hotspots - move your mouse over the pic below, see a hand and click; they only open up at the moment into new windows, but with time, they can be pop up windows to the exact size of the pics - I am sure you will get the picture!
One could be much more fancy - with 360 panoramas and JavaScript zoom, but that is as they proverbially say another story...
