Vanilla 2

Hi there
I just installed a venteed theme including prettyphoto for lightbox
I would like a very minimalist site and, therefore, removed any icon from pretty photo (navigation arrows, expand, social..) apart for left/right arrow fading above the picture
However, there is still a ~35px white section below picture. I tried to remove entirely the "pp-details" section, though that seems a very bad idea...

An example here
Any idea on how I could do it properly ?

Thanks a lot in advance
Jérome
