Once the extension is installed, simply use it in your code by :

In your model:

    return [
        [
            'class' => \maxmirazh33\image\Behavior::className(),
            'savePathAlias' => '@web/images/',
            'urlPrefix' => '/images/',
            'crop' => true,
            'attributes' => [
                'avatar' => [
                    'savePathAlias' => '@web/images/avatars/',
                    'urlPrefix' => '/images/avatars/',
                    'width' => 100,
                    'height' => 100,
                ],
                'logo' => [
                    'crop' => false,
                    'thumbnails' => [
                        'mini' => [
                            'width' => 50,
                        ],
                    ],
                ],
            ],
        ],
    //other behaviors
    ];
}

Use rules for validate attribute.

In your view file:

echo $form->field($model, 'avatar')->widget('maxmirazh33\image\Widget');

After, in your view:

echo Html::img($model->getImageUrl('avatar'));
echo Html::img($model->getImageUrl('logo', 'mini')); //get url of thumbnail named 'mini' for 'logo' attribute

If you use Advanced App Template and this behavior attached in backend model, then in frontend model add trait

use \maxmirazh33\image\GetImageUrlTrait

and use getImageUrl() method for frontend model too.
