I used this code on artforyoursake.com/galleries, where I had custom a custom post type with three custom taxonomies:
Here is the shortcode with just the taxonomies:
thumbnail_masonry taxonomies=’gallery_category’ gallery_category_terms=’10, 5’ gallery_category_field=’term_id’
This is the actual function call with all of the options:
proto_snap_masonry_shortcode(array(‘post_type’=>’afysgallery’, ‘excerpt’ => TRUE, ‘excerptheight’ => ‘150px’, ‘marginbottom’ => ’25px’, ‘columnwidth’ => ‘220’, ‘gutter’ =>’20’, ‘gridalign’ => ‘left’, ‘imagewidth’ => ‘220px’, ‘imageheight’ => ‘211px’, ‘hoverimage’ => TRUE, ‘hoverlink’ => ‘path to image’, ‘taxonomies’=>’gallery_category’, ‘showcaptions’ => TRUE, ‘captionheight’ => ’47px’, ‘gallery_category_terms’=>$id, ‘gallery_category_field’=>’term_id’));
