In fact the Viking probes are close to leaving the solar system but even that is debated. The image is a false color image constructed from near infrared wavelength radiation data collected from a satellite launched from earth into a 900 km orbit (560 miles) above the earth. They took the data that corresponds to the Milkyway Galaxy and combined it into a picture of what it would roughly look like from a distant observer. It is called a "false color" image because we cannot see radiation in the near infrared or microwave wavelengths that the satellite used. So they assigned colors (wavelengths) we can see to the wavelengths we couldn't. The description of the image on the NASA site you referenced states You are correct there has been no probe that has completely left our galaxy.

Man, they're keeping us in the dark here. And how did they film Star Wars? Man, they’re keeping us in the dark here.

This is not a picture from a probe, but probably a digitally made idea of what it looks like. You are right, no probe has been able to get beyond our galaxy.
