what should do? haven't found solution on google.

1. go in project @ command line , run :

   $ composer require intervention/image

2. go config/app.php :

in $providers array add service providers package.

intervention\image\imageserviceprovider::class 

3. add facade of package $aliases array.

   'image' => intervention\image\facades\image::class

4. windows users: edit php.ini , uncomment line:

   extension=php_fileinfo.dll

remember restart apache new php.ini take effect.

homestead halt homestead --provision
