This is funny considering the Buddha is supposed to have said to not make images of him, didn't he?
I think that is a common misconception. I don't think the Buddha ever said that. The first representations of the Buddha-Dhamma were footprints or the Dhamma Wheel, but not due to any rule.
The closest thing and maybe the cause of the misconception is one story where a monk admired the Buddha so much and just liked watching him. The Buddha advised him to admire the Dhamma (or something like that) and to show admiration by practicing.
