Thank you George. I think on the first page, they have default image, which already is very Big size image (almost page ful). When you change the size from the settings using styles for the theme e.g. 30 vh or 300 vh it changes can you can see the image there. What I intended was to change cover size independent of image. I may not want to use image as background at all. Just some text heading or remove it from some particular page. So your method may work in changing its size, but what if I want to remove it completely and have just text as heading or not at all? The setting we have is either cover is on or off and of fixed size for every page.
