Product gallery photos changed since update!

Hi there,
Since the update the product gallery photos display has changed majorly. Before they were nice small thumbnails in a small area under the main image where you could scroll through them, and now they are appearing all the way down the page and larger,but you can’t scroll through them either! it is a lot messier than before, any help into making them how they were before?
Thanks Yelena.
