ImageCache for Yii2

ImageCache for Yii2

Like the Image module in Drupal, this extension will resize your images on demand :-). If a thumb doesn't exist, the web server's rewrite rules will pass the request to Yii which in turn hands it off to ImageCache to dynamically generate the file., _(*1)

        'sourcePath' => '@app/web/images',
