DummyImage vs Icon Horse

DummyImage generates placeholder images on the fly from a simple URL pattern — width, height, background/text color, and format (PNG, GIF, or JPG) are all encoded in the path — with no signup or key. A live GET against the real host returned a genuine PNG carrying Access-Control-Allow-Origin: *, resolving cors unknown -> yes and reconfirming auth None.

Icon Horse fetches the favicon for any given domain — trying the site's own icon first and falling back through a chain of alternate sources so a usable image is returned almost every time — with no signup. A live GET against the real host returned a genuine PNG carrying Access-Control-Allow-Origin: *, reconfirming both auth None and cors yes.
