Plugin: Galleria Use Lightbox instead of Full Screen

I’d like to be able to click on image in gallery and get lightbox using Dark – No Fullscreen. Fullscreen creates images that are way too large. I’ve been searching the forums and have tried stuff out, but nothing has worked so far. I’m not even sure which plugin file I should be updating.

I tried adding these lines of code to galleria/galleria/galleria-1.2.9.js, but it had no effect. Thanks for any help!!

Galleria.loadTheme('galleria/themes/classic/galleria.classic.js');
Galleria.run('#galleria');
 $('<a>').click(function(e) {
Galleria.configure({trueLightbox:false});
Galleria.ready(function(){this.openLightbox();});
  }).html('</a><a>? Switch to fullscreen ?</a>

').appendTo('body');
Galleria.ready(function() {
    var gallery = this;
    this.addElement('exit').appendChild('container','exit');
    var btn = this.$('exit').hide().text('close').click(function(e) {
        gallery.closeLightbox();
    });
    this.bind('lightbox_open', function() {
        btn.show();
    });
    this.bind('lightbox_close', function() {
        btn.hide();
    });
});
