There is no worship of Gods or deities in Buddhism. The images you see are related to faith and many images deal with visualization practices to integrate meditation insight and practices. Buddhism doesn't negate God or Gods. What Buddhism teaches is a God or Gods, deity, what have you, cannot save you from your conditioning. You must put in the effort to free yourself from old habits and conditioning that blinds you from seeing reality as it is...God cannot save you from self destructive habits.

Buddhism does negate creator Gods, it is our own actions that create (the law of nature, cause and effect, karma) who we are.... However, the text I've read that heavenly beings like, devas, Gods and such, create karma even though their conditioning may be very good, giving them birth into the higher heavenly realms. They will accrue karma through their long life and eventually pass and the heavenly beings will be reborn into the lower realms like ours, which is called the desire realm...or the lower realms like the animal realm or the hell realms...Gods that are jealous, vengeful, speak of killing those who do not believe in them will probably be born as worms or hungry ghosts.
