I’m confused

Foobox and Fotomoto?

I use Wordpress 3.5, Next-Gen, Jusitfied Image Grid an as Lightbox "FooBox".
And now my Problem:
The Buy-Buttons apear only somtimes...
One i loo, the Button apears, an other day on the same Page, the Button(s) does not shown up...

i try different settings on the Fotomoto Site (FooBox isnt in the List), but it have no effect to the Site.

Any Idea?

You can see (or not ;-)) on fotoglut.de (all Images should have at least the "send Card" Button)
