I'm working on a website for an artist. He has many images that he would like a user to be able to sort and filter by custom taxonomy. In addition, he would like a user to be able to navigate through a hierarchical gallery with folders (that display a thumbnail) for each level of the hierarchy.
I started by creating a custom post type for "Artwork". I then created several custom taxonomies attached to this CPT. Each "Artwork" cpt has has a featured image and custom taxonomy terms. The archive is working well using these terms.
As far as the gallery, I'm not sure how to go about it. I'm currently accomplishing it with the NextGen gallery but then I can't sort the images by the custom taxonomies unless the client also uploads them to the CPT with the custom taxonomy terms which seems redundant to me.
Here is what the client sent along as a guide: Website Organization
