Measured on the live list (2026-09-29): after loading, the store tested every photo by loading it, three at a time with a second between batches: 932 photos, 132 MB by their Content-Length (the 77 IMB photos alone are 115 MB), for as long as the page stayed open, whether or not anyone zoomed in. All 939 photo URLs answered 200, and the canvas already loads only the photos in view and draws its grey box for any that fail, so the test is removed. A headless run of the real store with a counting Image stub: 12 photo requests in the first 3.5 s before, 0 after.
A group with no photo URL now gets none, instead of the stock "no image" photo, which answers 404. Today every group has a URL (a regional photo when it has none of its own), so nothing changes on screen.
The source picker only showed with two sources or more, and there has been one since the WordPress API and the CSV were dropped. It goes, with the two loaders, the CSV parser, their CSS, and the card component nothing imports. The bundle is 9.6 kB smaller (2.5 kB gzip).
