Product Photos disappeared?

Hi, I need some help trying to fx an issue that has arisen since the last update. When you go the the shop part of my website the pics are all there (for example Hand Dyed Fabrics) but when you click on a single product the pic disappears on the product page. You can only see the pic if you click on where it is meant to be and it comes up in a separate box (which you would normally do if you want to see the bigger pic)

Does/or has anyone know the solution to this problem? Im not sure if this happened before or after the update.
