Well I have an image of my wife - its called a photo. She is anything but unseen. Perhaps you should use a word different word from that of "image."

We have been discussing this issue in the context of religion and religious worship. Do you bow down to the image of your wife and prayer to her?
The prohibitions of images are always in the area of religion and religious worship and always in the context of bowing down to them and directing to them any other acts of worship that God receives and regards as acts of worship.
The golden calfs were understood to have been manufactured by the hands of Aaron with the gold supplied by the people bowing down to them. They were bowing down to them as VISIBLE REPRESENTATIVES of the Elohim that opened up the Red sea and delivered them from Pharoah. Hence, God condemns REPRESENTATIVE IMAGES of anything in heaven or on earth that receives acts of worship whether it is directed ultimately to God or not!
For example the lid of the ark is in the context of religion and religious worship but God never prescribed any kind of bowing to this lid or any other furniture designed and used in the tabernacle/temple. The ark was not a visible representation through which angels were prayed to or God was prayed to or they were to bow down before.
Roman Catholicism violates these very basic prohibitions when they argue that such visible images only act as visible representations that are used in worship of invisible things.
