Best way to handle item images and metadata for a simple shop‑style game?

Hi,

I’m working on a small web game inspired by running a tiny online thrift store, where players sort, price and display second‑hand items. I’d like some advice on the best way to handle item images and metadata (name, condition, tags, etc.) using the Kongregate API or common patterns you’ve seen work well.

Are there any recommended approaches or examples for storing and loading lots of small item records efficiently, and keeping everything easy to update if I add new items later? Any tips or links to relevant docs would be really appreciated.
