link to image is wrong

this is a test site:
http://video.balenaludens.it/

it’s part of a network.

There are no site plugins active and the few plugin activated at network level seems to create no problem (I deactivated each one and the issue remains)

Please see this page
http://video.balenaludens.it/italian-games-editors-aid/

the image at top and at the right is the same, but one works and the other NOT.

Please note the same page in the main site works well
