This package uses polymorphic relationships to easily attach images to models. Basically you just need to use one of the package's traits in your model and you are good to go(see Usage). What happens in the background is that the models are linked to the images by a MorphOne relationship and every time you persist a image into the associated table the file is written automatically using the selected driver (using Flysystem), or updated if needed.

To get started with Image Attacher, add it to your composer.json file as a dependency:

$ composer require cbcaio/image-attacher

After installing the Image Attacher, register the CbCaio\ImgAttacher\Providers\ImgAttacherServiceProvider in your configuration file (config/app.php):

'providers' => [
    // Other service providers...

    CbCaio\ImgAttacher\Providers\ImgAttacherServiceProvider::class,
],

In order to publish the configuration files run the following command

$ php artisan vendor:publish

This command will create 3 new files:

1. config/img-attacher.php : this file holds the Image Attacher configurations.

   • path_to_save: defines where images will be saved, relatively to the driver and local specified in the flysystem.php. This path will be parsed before being used. The :attribute references information about the attacherImage model while the :owner_class and :owner_id are relative to the owner class of the relationship. These are needed to organize folders and also to certify that the right image will be deleted.

     IMPORTANT: This path should be exclusively used by the package, do not put other files in the same folder otherwise they can be deleted by mistake.

   • processing_styles and processing_style_routines: the 'routine' represents a sequence of 'styles' and its needed methods. Each 'style' saves a copy of the original image with the modifications specified in its method. They can be used to save different versions of your original image automatically when you add an image to a model (the model can can have different 'versions'/'styles' of same image with only one relationship).

     • For example, the following code will save the original image and also a 'thumbnail version' of the same image in their respective parsed path_to_save with :style substituted by original_style and thumbnail:

          $model->addImage(uploaded_file,'default_routine');
          ....
           'default_routine' =>
           [
               'original_style' => function ($image) {
                   return $image;
               },
               'thumbnail' => function ($image) {
                  $image->resize(null, 500, function ($constraint) {
                      $constraint->aspectRatio();
                      $constraint->upsize();
                  });
                  return $image;
               },
           ]
       

2. database/migrations/2016_01_12_000000_create_attacher_images_table : this is a migration file to create the table which will hold the reference to your models in the MorthOne relationship and the information about the images.

3. config/flysystem.php : this file is relative to the Flysystem. How and where your files will be written is defined here. It is important to say that this package is only tested using the 'local' driver.

To start attaching images to your models you just need to use one of the available traits (currently only hasImage) in the model.

 class RandomModel extends Model
 {
     use hasImage;
 }

```php
    $upload = Input::file('image');
    $model->addImage($upload);
     // Directly from $request
    $model->addImage($request->file('image'));
     // With parameters
    $model->addImage($request->file('image', 'processing_style_routine','newfilename.jpg'));
```

```php
    $image = $user->getImage();
      // Path is relative
    $image->getPath('original_style);
    $image->getPath('thumbnail);
    
      // Url includes full path
    $image->getUrl('original_style);
    $image->getUrl('thumbnail);
``` 

```php
    // The same as adding, the package will identify if the model already has an image, delete the previous 
    images and update the relationship.
    $upload = Input::file('image2');
    $model->addImage($upload);
```

```php
    $model->deleteImage();
```
