section images not clickable

Hello there, On our site (staging.toerfietsleusden.nl) we want to show the sponsor’s logo’s. I tried for this the service section and the team section. Both sections are very usable for this. But in both sections the images stay clickable even if I let the link space empty. The link is to the front page. We only want to show the images of our sponsors without the clickable possibility. Can you give me css for that if it is possible? Kind regards Hans Hagmeijer
