Start album in fullscreen mode

You can load them as slideshow:
Say your album has id number 3, use shortcode:

[wppa type="slide" album="3"][/wppa]

or

[wppa type="slideonly" album="3"][/wppa]

Or use the shortcode generator as described here:

for more shortcode options

Thanks, but neither of these approaches even offers the option to view the images fullscreen, which is what I am wanting.

It is not possible to start in fullscreen lightbox mode.
It needs at least two mouseclicks or touch events.
Set the link on slideshow to lightbox ( Table VI-B5 ).
