Single Product image is way too big.

Dear people,
who can help me out?!
I have the plug in woocommerce installed on my website. But since a few days the main product image on the product page is too big. Normally is was aligned to the left of the description. But now there is 1 big full width image on top, and under that there is the description.

Look here: http://www.tolhuijs.nl/product/spool-deluxe/

Who can help me with this issue, to get things back to normal?

Thank you very much for you help!

Best regards
