Subject: [PATCH] Fix `Image.src` on Windows when it is a local file

`new URL("C:\path\filename.png")`
is treated as a valid URL, which it is not. `phin` subsequently tries
to fetch it, but `phin` and `centra` only supports http and https anyway.
Therefore `isValidUrl` will check also the protocol.
