I'm working on creating a gallery site to get my paintings back online, and I'm playing with methods of creating galleries from nodes with images, descriptions, and data about each painting.
So I want to create a view that pulls thumbnails from each painting content-type page, but the gallery views would be broken out by category (Portrait, Landscape, Still-Life, etc.).
So here's my question... In the Painting Page content-type would I add a text field with a select list of the categories, or make a Taxonomy of the categories and associate THAT with the content-type?
When it comes down to it... what's the difference--since you can easily make a custom field with the defined list or terms. Why use Taxonomy?
