Which means what? That Jesus is the Father? No. Jesus is the image of God and God's presence was indwelling within him.
An image is a representation of a person or thing, not the thing itself. This basic English negates Jesus from being God. If Jesus is the image of God then he cannot be God and worshiping him as God is to worship an image of God in His place, which is idolatry.
If they could not see the Father in Jesus, through his nature, works, and words, they weren't looking. That is the point of Jesus's words. It's very simple.
