When you want to display a slideshow of images there are quite a few choices for plugins. See Galleries and Slideshows.
But I want to be able to use both of them in my sites. So oik provides two alternative shortcodes which support peaceful co-existence of the plugins and the ability to choose the slideshow you actually want.
The shortcodes are:
[ ngslideshow] – for the NextGen gallery slideshow
[ gpslideshow] – for the Slideshow gallery pro slideshow
