In Portfolio+ I use a custom post type for portfolio items and a custom taxonomy for portfolio categories. When someone views a portfolio archive page all of the portfolio featured images are displayed, and when someone goes to a portfolio category all the featured images of posts in that category are displayed.
But a common request I’ve had is for a template that displays all the portfolio categories with thumbnail images for each of the categories. This would allow someone to easily link to different sections of their overall portfolio (for instance, “Photography”, “Water Color”, “Sculpture”) rather than having them all show up in one jumble of the main portfolio archive template.
This gets a bit tricky because there is no easy way to associate an image with a taxonomy term (though Michael Field’s Taxonomy Images Plugin has made it work).
I decided the best route would be to just display all of the categories, and use the featured image from the most recent post in each category. This obviously won’t be the perfect solution for everyone (some may want to use a completely different image for the category thumbnail), but for most users I think it works well and is a dynamic way to show off new work.
