Hinduism is always open to interpretation and that is the inherent beauty of the religion. It does not enforce any laws on anyone. Even an atheist can find a solution for this ways in the scriptures of the Hindu Text. Regarding your 33 crores of God, that is also interpreation on how people want to worship almightly.
Just like a company which is known by his name and internally by CEO, thousands of employees, Hinduism functions in the similar way so as to make the people tolerant by worshipping different interpretations of the same almighty.
Essence of Hinduism is beauty and if you have come to a conclusion about it badly just by seeing images, you must convert to some other intolerant relgion which says "worship only like this and nothing else" and repent later by getting some hits from them.
