Hotel listing pages are almost entirely photography: a room gallery with 10-25 shots per room type, plus lobby, pool, restaurant, and a hero banner — often pulled from a professional shoot at 6000px wide and 8MB per file. Most guests open those pages one-handed on mobile data while comparing three properties at once, so an image-heavy listing loses the booking to whichever page renders first. Compress each photo to the size the gallery actually displays, keep the detail that sells the room, and the listing stops punishing guests on slow connections.
