I need help editing the home page of my WordPress run website. I did not create the site originally, but I run it now.
This is my website: http://www.gpaxterras.org
I need to know how to edit the main image up top with the keystone and the words "Greater Philadelphia Area Xterras".
I searched in the theme section, but I am not well versed in the WordPress software.
Please help me and thank you.
