You say I am not understanding. It is true that I do not understand how you can believe what you do. You do not understand how I believe what I do. That is not the same as not understanding. There are many people who find graphic photographs and descriptions of the human body offensive. As a doctor, I can be aware of this, and yet make medical textbooks to spread knowledge and discuss facts without intending to offend. I would say that those who posted to Wiki are aware that the images can and will offend - but that is not the same as an intent to offend, which is childish. I'd say they believe that the things they have posted are of historical value and contribute to the spread of knowledge, which they see as a noble thing. That you are deeply offended and profoundly disagree does not mean that the authors intended to offend, or that their actions are explained away through lack of understanding on their part. You lack understanding of their viewpoint as surely as they do yours.
