Gravatar has become really easy to use custom avatars across multiple platforms. What if your users don’t use Gravatar or have an avatar, a default avatar is loaded in it’s space. It is recommended you brand your default avatar to your website.
First, lets make sure you have a custom avatar image ready. If you do not, make one in the dimensions of 64×64.
Second, name your avatar whatever you want, let’s say “custom-avatar.jpg”. It’s entirely up to you to name it what you want.
Thirdly, upload your image to wp-content/themes/your-theme/images/.
Lastly, open wp-content/themes/your-theme/functions.php and add the following:
// Adds a custom default avatar
if ( !function_exists(‘fb_addgravatar’) ) {
function fb_addgravatar( $avatar_defaults ) {
$myavatar = get_bloginfo(‘template_directory’) . ‘/images/custom-avatar.jpg’;
$avatar_defaults[$myavatar] = ‘Your Name’;
return $avatar_defaults;
}
add_filter( ‘avatar_defaults’, ‘fb_addgravatar’ );
}
Note: Replace “custom-avatar.jpg” with whatever you named it. Also replace “Your Name” with a name to describe the image – this is normally your website name.
Now go to Settings —> and click on “Discussion”, you will be able to see the custom avatar you just added. You can now choose the newly added custom avatar as the default avatar shown.
