set in .env
APP_URL=your_domain

set in config.app.php
  'url' => env('APP_URL', 'your_domain'),

in controller
$imgLogo = config('app.url') . '/your_folder/your_name_logo';

in blade
<img src="{{ $imgLogo}}" width="200">

So DOMPDF for render HTML only and render image not use public_path or asset
