Featured image behavior

Hi guys,

I want to remove the lightbox link from all featured images in single posts. I’ve browsed the board and found this CSS solution:

.big-preview.single-big { pointer-events: none; }

The problem is though that it not only disables the featured image click in single view, but also in post listings. For my homepage, I use custom listings (http://datenschmutz.net)

Is there a way to *only* remove the lightbox link in single post view but to keep the image linked in listings?

cheers, Ritchie
