...we have to develop the perfections to come in contact with a Buddha.
But how could you know which are the perfections without Buddha to tell you in a first place?
Once we have the teaching, which is the result of our good fortune (a Buddha being there) and our development, we have to put it into practice and get the results.
There is no such thing as good fortune. It is only a label for a pleasant result, and it too depends on its causes and conditions.
Hell beings are unfortunate, there's little they can do that I know of. What virtue can a being whose only experience is torment do? I honestly don't know much about hell. I can't exactly look out my window and see hell and make observations about it. But I know when I am in a lot of pain, it's hard to do good things, but bad things come easily.
What i was trying to say is that Buddhas images are not self-existentially a virtuous. They do benefit, but only if you can conceptualize them as Buddhas images. If you are a termite, only benefit that could you get from them is a tasty paper meal. Assuming that colors are not poisonous of course.
