Site Icon Fallback

Site Icon Fallback Set a Site Icon in Settings → General. Get /apple-touch-icon.png, /favicon.ico and /favicon.png answered from it, instead of 404. WordPress declares the Site Icon in the page head, but many clients never read that markup. Applebot, Safari's Favourites thumbnailer, Add to Home Screen, Reading List, and the link unfurlers in Slack and iMessage request icons straight from the domain root. This plugin answers them. Nothing is hardcoded and no files are copied into your web root. Change the Site Icon and the root paths follow. What it does Declares the sized icon tags. Core emits one apple-touch-icon link with no sizes attribute, so a client after a specific size has no exact match to pick. This plugin considers 120, 152, 167 and 180, and declares each size backed by a genuinely different image. Works on any host with no configuration. Answers the root paths. Requests for /apple-touch-icon.png, /favicon.ico and /favicon.png return the icon at the size asked for — a 200 with the image bytes, an ETag, and a day-long Cache-Control. It serves bytes rather than redirecting, because nothing guarantees an icon fetcher follows a redirect. This half needs those requests
