Upload your image to
includes/templates/YOUR_TEMPLATE/images/.

Edit includes/languages/english/YOUR_TEMPLATE/header.php to reflect the new logo name and dimensions.

Anywhere you see a /classic/ folder, you can create a folder for your custom template. You can copy the necessary files from either the /classic/ folder, the /template_default/ folder or the parent folder.
