Theme Horse

Hi ksuna24,

You can add one header logo and one header image also.
to add header banner then go to dashboard-> appearance -> header (from here you may add header image)

For the logo
go to dashboard-> appearance -> theme-options -> design options -> header logo

If you are still not satisfy then you may change it from theme folder -> inc -> structure -> header – extension.php on line no 341

From here you may change the code.

Thank you!
