GK4 tab - link

hi,
I have invested in the meantime very much time to find out, how can define the link for the gk4 tab article.
on the frontbae in the gh4 tab i will be show article which are in some categorie. i would like create a link of this image, that jump to a breezingform which i created. i would like gice them image an hard link. but the link will be ignored.

how can i disable the link and add my own link?

i found ou,that all links on the frontpage doesnt works in the module. but if i display the module on an other site the link works. why?

please, has somebody an idee?
