But the image isn't a photo of the result. It's an unrelated image that vaguely looks like what you could make, with a different recipe, and with some skill.
The main pic looks like a classic British leg of lamb. So what’s your point? Why post such low quality slop?
As I said I can see the value in this similar to Pinterest boards. It is directionally correct and serves most of the value that a picture does. No perfect but probably close enough for the general audience.
