[WP] Creating RoyalSlider from images attached to post
Video shows how you can override default WordPress gallery with
RoyalSlider. You can create configuration once and reuse it for
every next post just by adding royalslider attribute to gallery
Since version 3.0.8 you can enable RoyalSlider on all of your
[galleries] (without adding royalslider attribute) by
checking an option on RoyalSlider global settings page.
Please note that this type of RoyalSlider doesn't have any
caching mechanism (in comparison with
other types, like "Custom" or "Flickr"), so it's recommended to use plugins that cache contents of post, like W3 Total Cache.
Plugin installation video can be found here.
