[TYPO3-commerce] Click enlarge image not working

[Andrej Radonic]

Dear list,

image zoom in detail view is not working with our installation of 
commerce 0.98, TYPO3 4.2.x

TS-Setup:

plugin {
  tx_commerce_pi1 {
   singleView {
    products {
     fields {
      images {
       imageLinkWrap < tt_content.image.20.1.imageLinkWrap
       imageLinkWrap.enable >
       imageLinkWrap.enable = 1
      }
     }
    }
   }
  }
}

Any ideas where to look for?

Thanks, kind regards
Andrej
