Opus 32
This portfolio page demonstrates the display of more than one photo.
You can show the thumbnails:
[wppa type="thumbs" album="54"]
Or a slideshow:
[wppa type="slide" album="54" size="0.5" align="center"]
Or even a non-interrupable slideshow without any surrounding stuff:
[wppa type="slideonly" album="54"]
If this (portfolios) is the major application of WPPA+ on your site, you might disable the display of breadcrumb navigation and other bars. See the Photo Albums -> Settings page for more options.
