As You have stated in comment that You have disabled header images, but its still returning default image.
Explanation : It depends on how it was coded in the theme by the developer. For an instance, it seems like if you disable all header images, it returns Default header set by the developer / theme.
Now, Even if the function header_image() doesn’t returns anything, <img> tag will be there and a placeholder or Alt Text will appear on the page, that is not a proper solution/way to remove header.
