Загружаю картинку в yii2 не показывает?

покажите путь к картинке на сервере?

Vlad Osadchy, как я прописал путь?
щас я покажу весь код который я писал для прогрузки картинки

public function actionSetImage($id)
{

$model = new ImageUpload;

if(Yii::$app->request->isPost)
{
$product = $this->findModel($id);

$file = UploadedFile::getInstance($model, 'image');

if($product->saveImage($model->uploadFile($file, $product->img)))
{
return $this->redirect(['view', 'id'=>$product->id]);
}

}

return $this->render('image', ['model' => $model]);
}

теперь другой файл

namespace app\models;

use Yii;
use yii\base\Model;
use yii\web\UploadedFile;
//use yii\db\ActiveRecord;

class ImageUpload extends Model{

public $image;

public function rules()
{
return [
[['image'], 'required'],
[['image'], 'file', 'extensions' => 'jpg,png']
];
}

public function uploadFile(UploadedFile $file, $currentImage)
{

$this->image = $file;

if($this->validate())
{

$this->deleteCurrentImage($currentImage);

return $this->saveImage();

}
}

private function getFolder()
{
return Yii::getAlias('@web') . 'upload/';
}

private function generateFilename()
{
return strtolower(md5(uniqid($this->image->baseName)) . '.' . $this->image->extension);
}

public function deleteCurrentImage($currentImage)
{
if($this->fileExists($currentImage))
{
unlink($this->getFolder() . $currentImage);
}
}

public function fileExists($currentImage)
{
if(!empty($currentImage) && $currentImage != null)
{
return file_exists($this->getFolder() . $currentImage);
}
}

public function saveImage()
{
$filename = $this->generateFilename();

$this->image->saveAs($this->getFolder() .$filename);

return $filename;
}

}

ещё другой файл
public function saveImage($filename)
{
$this->img = $filename;
return $this->save(false);
}

public function getImage()
{

return ($this->img) ? 'upload/' . $this->img : '/no-image.png';
}

public function deleteImage()
{
$imageUploadModel = new ImageUpload();
$imageUploadModel->deleteCurrentImage($this->img);
}

public function beforeDelete()
{
$this->deleteImage();
return parent::beforeDelete();
}
