Hi, Chris —
All worship of Jesus should be directed to His Person, not His image. Jesus is Himself the image of the invisible God (Colossians 1:15); He is the image we should worship. Any attempts to conjure up images of Jesus in our minds should just be means of helping us connect with the Person of Jesus. Our worship terminates, as it were, not in the image, but in the Person of our Lord and Savior. It's OK to worship through an image, e.g., to worship Jesus through a physical icon, but again we understand that the worship terminates in the Person of Jesus Christ, not in any image of Him.
We call to our mind the images of Jesus in prayer and worship it as God.
No it doesn't to me but I rather doubt that people in practice actually do this, even if they say they do. Surely they understand that Jesus is in Heaven, and is not an image in their mind, and that they are worshipping the Jesus in Heaven, using the image as an aid, not worshipping their own imagination.
