We have recently updated all of the WordPress themes we offer (both free and premium) to support the custom logo functionality.
In this way, you can set image logo and site title and tagline (screenshot above) using the recommended WordPress guideline for implementing that functionality, Reference: Codex Theme Logo.
If you want to display only the logo, you will have to uncheck the ‘Display Site Title and Tagline’ checkbox., learn more from the updated documentation:
Of course, the premium themes have the additional theme options such as setting different logo image size for different screen resolutions.
Note: If you have purchased a Premium WordPress Theme from us in the last year, you can download the new theme version using the download link from the email, already received by us with a download link of the theme.
