Problem with multiple photos on product page after change image size

[tobyisabelle]

Hi! 

 

I changed the large_default image  size in my store to 670 px X 670 px from the default prestashop size.After that i regenerated the thumbnails. 

 After that my product pages are no longer showing my additional photos. it only shows my cover photo. 

 

http://www.therepublicmarket.com/Cheryl/en/frontpage/883-gold-spade-on-black-and-white-stripes.html this is an example. i uploaded 3 images.

 

can anyone advise? thanks!
