Why do some images render from the bottom? I have seen them in the past but I have never thought of it much. Today I was browsing this page of ZeusEdit editor and middle-clicked on one of the screenshots and noticed that the image loaded from the bottom. I am asking since I searched here and did not find any similar questions.

Middle-clicking opens an image in the new tab.

Because in the image file, they are stored from the bottom up, like Microsoft's BMP format.
