Views: Taxonomy Term View: Display only one node per taxonomy term.
Today I was setting up a website that was using FlickrSync to pull images from Flickr. FlickrSync creates one node per image and uses Flickr's tags as taxonomy terms. Perfect.
I created a new Term view to pull all taxonomy terms associated to the 'Gallery' vocabulary I had created. The problem I ran into was that the view pulled ALL image nodes tagged with each gallery term. This was not what I was looking for. Instead, I wanted a list of each term and one image node, not all nodes.
