This couldn't happen, an exe file can't just run when loaded by a piece of software it would have to be explicitly interpreted as an executable program which Windows does to files named .exe but which some random image viewer wouldn't if you renamed it to jpeg.

Instead if would just check the file contents against the image formats it knows, and then give up when it doesn't find a match.
