about

nx_imgfacts.nx -- per-asset DIMENSIONS + bytes for a gathered corpus, and a real GALLERY page. The operator's question is a product question, not a plumbing one: "are we getting too small of images?" A contact sheet cannot answer it -- every tile is normalised to the same box, so a 120px thumbnail and a 3000px original look identical. This decodes each asset for its TRUE pixel size, reports the distribution, and emits a gallery that shows every image at its own scale with its dimensions stated. usage: nx_imgfacts <dir> <out.html> <url-prefix> [title]
