remove wp user avatar from TinyMCE bar

Hi, I assume you found the tutorial here or something similar:

function myplugin_tinymce_buttons($buttons)
 {
      //Remove the text color selector
      $remove = 'forecolor';

      //Find the array key and then unset
      if ( ( $key = array_search($remove,$buttons) ) !== false )
		unset($buttons[$key]);

      return $buttons;
 }
add_filter('mce_buttons_2','myplugin_tinymce_buttons');

Change ‘forecolor’ to ‘wpUserAvatar’ and wrap the add_filter in an init function (also the button is in the primary toolbar, so no _2):

function wp_user_avatar_remove_tinymce(){
  add_filter('mce_buttons', 'myplugin_tinymce_buttons');
}
add_action('init','wp_user_avatar_remove_tinymce');

Also, to clarify, this code goes in the functions.php file in your theme.
