How to change the logo in the Jollyness theme

Hello, I am trying to change the logo in the Jollyness Demo and can't find where it is located. Thank you.
Hello, How can I change the Favicon for the Jollyness Theme? Thank you.
I’m answering my own question: To be safe, I used both methods I changed the logo here and it works. By uploading the image. http://www.YourSite/Demo/sites/all/themes/jollyness/logo.png http://www.YourSite/Demo/misc/favicon.ico Another way was to go to Appearance > Settings of Template > Drupal Core > Logo Image Settings > Path to custom logo. Shortcut to Icon Settings > Path to custom icon
To change the logo,please go to http://your-domain/admin/appearance/settings/jollyness then select drupal core,uncheck default checkbox then you can upload you new logo or favicon icon Thanks
