This mostly… but not only, applies to Pinterest. Many, probably most, images on this site can be opened in another tab where they are shown in full resolution. Meaning you can actually see detail and read text. I’m constantly seeing these cool looking ads on Pinterest, I really would like to see them in a better resolution, where I can actually read the text. But usually what you initially see, is what you get. Yes you can magnify them, and that can sometimes help. But it’s not sharp.
