Remove Caption and next/previous arrows from Colorbox for Node
The only way I found to do this was to change my theme css file (I use an Omega >theme so used global.css) and add:
  
  #cboxPrevious, #cboxNext {
        width:0;
     }
  
  I initially tried display:none but something is overriding it.


display:none works if you use !important
