Next to india. Hinduism is a problematical case due to the lack of a single founder and the mythical status of say Krishna (images exist). Still there appear to be no problems with images of Guru Nanak Dev and I doubt the Sikhs are completely divorced from the rest of indian culture.

Hinduism is the last remnant of the old Indo-European faith that relished images of the deities. If we applied the principles of Islam to the article on Hinduism to to articles on Hindu deities, it would be grossly inappropriate. What is being asked for is application of Islamic principles to the key articles about Islam. I think it is a matter of respect, of avoiding offense, of authenticity.
