I've got AutoNav 1.49a installed. I am trying out the NextGEN Gallery plugin, which is the most popular gallery in the WordPress world, and one of the most popular plugins period.
The AutoNav changelog says,
"New filters for extensions like NextGEN Gallery thumbnail support, and for taxonomy-images plugin. These are then implemented in auxiliary plugins, or theme files."
So, how exactly do I get AutoNav to display thumbnails from NextGEN galleries? Where is this "auxilliary plugin" you mention, does it exist?
