I put this together the other night. It's a placeholder service with a bunch of pretty nouns (people, places, things). Powered by imgix, with lots of photos from Unsplash.
@paulstraw This looks fantastic, now how this code entered?! I think "random=hello" isn't HTML so it looks like it's only for people who write more advanced code, many who could make use of this don't code at all. Lorem Pixel suggests it is HTML but I would have thought the image URL end in an image filename.
