I have implemented a customized version of effervescence_plus on my site. When I first tried the search, even though the profile is set to slimbox the images took you to an image page. Images and slimbox work properly everywhere else.
I looked at the generated code and it was not generating the rel link (rel="lightbox[]") so I modified the image thumb generation code to match that of the albums and made sure the search page is loading the js and css that should be called. After this the click on an image from a search page generates the image but not in the page nor in an actual slimbox.
I have compared the generated code from the albums pages and the search pages and there are no differences that I can find in the calls to load nor the image sections and the lightbox rel call is there.
Since this is an included theme and search is implemented by default I figure someone must have run into this.
you can see the issue by going to:

look at an album and you will see slimbox working properly. Do a search on, say, "Germany", and then click an image and you will see how it is borked.
What am I missing? All help appreciated.
