Provide an option to hide Empty Galleries (i.e $gallery->count = 0)

I've added a setting on the settings form [image_gallery.module]

+  $form['gallery']['image_gallery_list_empty_galleries'] = array(
+    '#type' => 'checkbox',
+    '#title' => t('List empty galleries'),
+    '#default_value' => variable_get('image_gallery_list_empty_galleries', 1),
+    '#description' => t("Checking this will always list galleries, even if they are empty."),
+  );

which is used during while theming function theme_image_gallery($galleries .. to
NOTlist a gallery when it's $gallery->count is ZERO

+      if(!variable_get('image_gallery_list_empty_galleries', 1) and !($gallery->count)){
+        //don't display empty galleries
       }
