Installation:

0. Download and extract extension somewhere in your application(in this guide into extensions/imageAttachment). Also available in composer.

1. Add ImageAttachmentBehavior to you model, and configure it, create folder for uploaded files.

   :::php
   public function behaviors()
   {
       return array(
           'preview' => array(
               'class' => 'ext.imageAttachment.ImageAttachmentBehavior',
               // size for image preview in widget
               'previewHeight' => 200,
               'previewWidth' => 300,
               // extension for image saving, can be also tiff, png or gif
               'extension' => 'jpg',
               // folder to store images
               'directory' => Yii::getPathOfAlias('webroot').'/images/productTheme/preview',
               // url for images folder
               'url' => Yii::app()->request->baseUrl . '/images/productTheme/preview',
               // image versions
               'versions' => array(
                   'small' => array(
                       'resize' => array(200, null),
                   ),
                   'medium' => array(
                       'resize' => array(800, null),
                   )
               )
           )
       );
   }

2. Add ImageAttachmentAction in controller somewhere in your application. Also on this step you can add some security checks for this action.

   :::php
   class ApiController extends Controller
   {
       public function actions()
       {
           return array(
               'saveImageAttachment' => 'ext.imageAttachment.ImageAttachmentAction',
           );
       }
   }

3. Add ImageAttachmentWidget somewhere in you application, for example in editing from.

   :::php
   $this->widget('ext.imageAttachment.ImageAttachmentWidget', array(
       'model' => $model,
       'behaviorName' => 'preview',
       'apiRoute' => 'api/saveImageAttachment',
   ));

4. It is done! You can use it now.

   :::php
   if($model->preview->hasImage())
       echo CHtml::image($model->preview->getUrl('medium'),'Medium image version');
   else
       echo 'no image uploaded';
