I am not sure what steps i would take to fix it.
The problem can be seen here:
http://gjellervand.s-innovations.dk/ (click one of the images).
Following code is appended to the site:
<divid="lbCenter"style="display: none;"><divid="lbImage"><divstyle="position: relative;"><aid="lbPrevLink"href="#"></a><aid="lbNextLink"href="#"></a></div></div></div>
<divid="lbBottomContainer"style="display: none;"><divid="lbBottom"><divid="lbOverlay"style="display: none;"></div><divid="lbCaption"></div><divid="lbNumber"></div><divstyle="clear: both;"></div></div></div>
I can find a fix, if its a good one i do not know, but the following
<divid="lbOverlay"style="opacity: 0.8;"></div>
should be placed before above two divs instead of in the last one?
