can't see pictures on iPad, only on my Mac

Hi, have made a website in Fotografie theme. Have made a new page on the website and chosen template “Photograhy Portfolio” for my pictures. Here's the result: http://www.ecocom.dk/fotogalleri/olsens-oekofrugt/ It looks fine in Safari on Mac, but on my iPad (Safari and Chrome), there's no photos! Only small dots 5-10 pixels in the left side of the page... Have un-installed Wordpress and installed again, but same result. A bug in Word Press ? Hope someone have an answer.
