I am using Mandigo Theme. I want to change the header image but i can’t find it how. I also search in the internet but i can’t find it too. Finally, i try to do this :

• Open image with image editor i like
• resize image in 737 x 226
• save as head.jpg for first image
• resize image in 961 x 226
• save as head-1024.jpg for second image

Next, i copy head.jpg and head-1024.jpg into :  /public_html/wp-content/themes/mandigo/schemes/green/images (for example in green folder)

Also i  copy both of  the new image again into each color folder. And then i can see the header image already changed.
