I've used quite a number of Styled Themes but I've never had such difficulty putting a header image in before. I've searched this support section and tried everything that has been said and either my header image doesn't show up at all, or it shows up full width but only about 1/5th the height, or (if I use meta slider) it shows up too small to fit the width of the slider or doubled (one too small and one full size).
Why should I need to add a widget (possibly even install a new plugin) simply to add header? It seems counter intuitive.
Can you help me to add my header?
