Find on line 103 of functions.php:
define(‘HEADER_IMAGE_WIDTH’, 900);
define(‘HEADER_IMAGE_HEIGHT’, 160);
change the sizes to whatever width and height you want.
Add this or whatever id your header has to your style.css:
#custom_header {
width: 900px;
height: 160px;
}
Upload your custom header to the proper image folder, likely under ‘your theme’ ‘images’
Mark sure your widths and heights match and it should work like a charm!
