its for Evo, I always use EvoGallery which kinda works the same, not sure which one this is, looks like maxigallery.
Evogallery has a own tab function.
Add in the demo_rules:
mm_widget_evogallery('4','','','3');
4 = module id, 3 is template id.
Evolution user, I like the back-end speed and simplicity
