Points of view on images are subjective and what one person likes another may not. I would not object to using the one with the red parathyroid glands in the article. Nevertheless, I saw an image recently (forget where) that had yellow parathyroid glands and I looked quite good.   
Here is a black and white image from Gray's 1918. File:Anatomyofhumanbo1918gray 1280.jpg. It has a better resolution that the similar image in the gallery. Any comments?
