title: Images created with factory faker get deleted when stored in storage/public/images folder
body: <p>I'm trying to populate my database with fake images but when faker save it on my images folder after one second it got deleted and on my database field I get 0</p>
  
  <p>I can visit <a href="http://lorempixel.com/" rel="nofollow noreferrer">http://lorempixel.com/</a>, also ping it with no problem.</p>
  
  <p>Also tried this: <code>$faker-&gt;image(storage_path('app/public/images'), 800, 800, 'nature', false),</code></p>
  
  <p>And changing lorepipsum url like here: <a href="https://github.com/fzaninotto/Faker/issues/1715" rel="nofollow noreferrer">https://github.com/fzaninotto/Faker/issues/1715</a>
  (<a href="http://placekitten.com/" rel="nofollow noreferrer">http://placekitten.com/</a> and <a href="http://placekitten.com/" rel="nofollow noreferrer">http://placekitten.com/</a>)</p>
  
  <p>this is my post factory code:</p>
  
  <pre><code>&lt;?php
  
  /* @var $factory \Illuminate\Database\Eloquent\Factory */
  
  use App\Post;
  use Faker\Generator as Faker;
  
  $factory-&gt;define(Post::class, function (Faker $faker) {
      return [
          'title' =&gt; $faker-&gt;sentence,
          'body' =&gt; $faker-&gt;text(600),
          'slug' =&gt; $faker-&gt;slug, 
          'metaTitle' =&gt; $faker-&gt;sentence,
          'metaDescription' =&gt; $faker-&gt;sentence,
          'user_id' =&gt; App\User::all(['id'])-&gt;random(),
          'postImage' =&gt; $faker-&gt;image('public/storage/images',640,480, 'nature', false),
          'visible' =&gt; $faker-&gt;boolean(85),
          'favorite' =&gt; $faker-&gt;boolean
      ];
  });
  </code></pre>
  
  <p>It should store the image on my storage/public/images folder and give me a random slug.jpeg, but instead is removing it and giving a 0</p>
  
  <p><strong>EDIT:</strong> Have found if i dd() the faker->image comand it returns false, dunno why...</p>
