The auto index can list anything.
As explained elsewhere, albums will only be listed by the auto index when they contain assets recognized by the index. Most non-TTG galleries will not create these assets, preventing them from appearing in the auto index. However, you can force the auto index to recognize any folder – a gallery, a folder containing another page, or even list an external URL – by manually adding the
autoindex.xml and (optionally)
/thumbnails/ folder to a folder within the auto index target location.
The TTG CE3 Auto Index Enabler utility allows you to generate the necessary information and thumbnail image(s) from within Lightroom's Web module.
To use TTG CE3 Auto Index Enabler, install it as you would any other web engine, then select it from the Layout Style list in the Web module. The instructions for use are self-contained and will be displayed in the Web module.
TTG CE3 Auto Index Enabler is included in all purchases of TTG CE2 Auto Index and TTG CE3 Pages.
