When we talk about copyrights, the normal thing is that any work that is done by a person is copyrighted unless and until he is not bothered and put on his free will. We know that the " any religious image/ figure of God or videos on religious script" is purely the "original work" of people say artiest, actors, cameramen, or any other involved in it.
As the pictures, statues or images of God is either the property of the religious place like Temple, Churches, Mosques, etc as these are clicked or made as per their understanding, knowledge, study or source. Some images clicked or made may be as per order or with permission of the caretaker thus it is either their original work or work done on hire. As both these category fall under remuneration, and thus falls under copyright status.
But when we talk about copyright of a picture of image of God, there are hundreds or thousands of pictures/images of Krishna, Ram, Sita, Hanuman, Jesus, Mother Mary, St. Joseph, etc on the internet already uploaded or available that is published everday. Some have copyrights while some are free thus one needs to choose the appropriate one.
