how can I change the size of the header image. Basically what I do is using the featured image as header image, because I see no better option and don't want to create a slider for every page. The Problem is, that the image is only about 200px high and I want it to be higher like on www.guppyfriend.com. We did it there but I cannot find the option anymore to do it on our second home page.
Would be great if you could help me out.
