Did you know that Faker can generate not only text values but also IMAGES? See avatar
field here - it will generate 50x50 image:
$factory->define(User::class, function (Faker $faker) { return [ 'name' => $faker->name, 'email' => $faker->unique()->safeEmail, 'email_verified_at' => now(), 'password' => bcrypt('password'), 'remember_token' => Str::random(10), 'avatar' => $faker->image(storage_path('images'), 50, 50) ];});
