 Hi, it would be really great to be allowed to filter the gallery classes.

 Here's what I suggest :

 instead of :


 {{{
         $size_class = sanitize_html_class( $atts['size'] );
         $gallery_div = "<div id='$selector' class='gallery galleryid-{$id}
 gallery-columns-{$columns} gallery-size-{$size_class}'>";
 }}}

 rather use


 {{{
         $classes_str = null;
         $classes = array(
             'gallery',
             'galleryid-'.$id,
             'gallery-columns-'.$columns,
             'gallery-size-'.sanitize_html_class( $atts['size'] )
         );

         $classes = apply_filters('gallery_classes',$classes,$attr);

         if (!empty($classes)){
             $classes = array_filter($classes);
             $classes_str = " class='".implode(' ',$classes)."'";
         }


         $size_class = sanitize_html_class( $atts['size'] );
         $gallery_div = "<div id='$selector' $classes_str>";
 }}}
