Is This Plugin The Solution for my eCommerce Site?

Hello,

I’m building an eCommerce site for digital revivals of antique fonts. Each font is tagged with the original designer and/or producer, period of introduction, style classification and (frequently) a style variation.

I use a plugin that supports tags for WP pages; it does not display the tags. Likewise, the eCommerce plugin (Easy Digital Downloads) supports tags and does not display them.

The images to be displayed are one-line grayscale type specimens. I need a plugin that can do these things in the sidebar:

•Detect the ID of the image displayed on a product page.
•List and link the tags assigned to it.
•Exclude all other tags.

Clicking one of the tags would then execute these functions:

•Fetch all specimens with the same tag.
•Display them with only titles or WP captions.
•Exclude all else: text excerpts, thumbnails, etc.
•Link each specimen to its product page.

Examples

http://bazaar.typeheritage.com/xyz/one/ (typical product page)
http://bazaar.typeheritage.com/banner/ (manually compiled specimens of style variation)

Can the Tags for Media Library plugin perform this magic?

If so, can you recommend a basic gallery plugin? I looked at JetPack Carousel—it seems “overkill” for my needs (Slider WD is adequate).

I also tried NextGen and several others that deal with thumbnails and vertical layouts with excerpts, not original images with one per row and only one column.

The WP gallery function is a styling nightmare (stubborn ugly borders surround specimens) and does not support tags.

Many, many thanks for your advice
