Just spend an hour or so digging into PP for a border hack..
Just add to your page after:


/* PrettyPhoto CSS hack
** example: change 20px default border to 10px
*/
.pp_top { height: 10px; }
* html .pp_top { padding: 0 10px; }
.pp_top .pp_left { height: 10px; width: 10px; }
.pp_top .pp_middle { height: 10px; left: 10px; right: 10px; }
.pp_top .pp_right { height: 10px; width: 10px; }
.pp_bottom { height: 10px; }
* html .pp_bottom { padding: 0 10px; }
.pp_bottom .pp_left { height: 10px; width: 10px; }
.pp_bottom .pp_middle { height: 10px; left: 10px; right: 10px; }
.pp_bottom .pp_right { height: 10px; width: 10px; }
.pp_content_container .pp_left { padding-left: 10px; }
.pp_content_container .pp_right { padding-right: 10px; }

/* change 40 to (2 x your border width)
** search in jquery.prettyPhoto.js: line 497:
** containerWidth:Math.floor(pp_containerWidth) + 20, // was 40
*/


Edit the JS and you should be fine.
Thanks Stephane, for this great plugin.
