Add migration to create table for images:

class m150318_154933_gallery_ext extends \sashsvamir\galleryManager\migrations\m140930_003227_gallery_manager
{
}

Or better - copy migration to your application.

Add GalleryBehavior to your model, and configure it, create folder for uploaded files.

public function behaviors()
{
    return [
         'galleryBehavior' => [
             'class' => GalleryBehavior::class,
             'type' => 'product',
             'extension' => 'jpg',
             'directory' => Yii::getAlias('@webroot') . '/images/product/gallery',
             'url' => Yii::getAlias('@web') . '/images/product/gallery',
             'versions' => [
                 'small' => function ($img) {
                     /** @var \Imagine\Image\ImageInterface $img */
                     return $img
                         ->copy()
                         ->thumbnail(new \Imagine\Image\Box(200, 200));
                 },
                 'medium' => function ($img) {
                     /** @var Imagine\Image\ImageInterface $img */
                     $dstSize = $img->getSize();
                     $maxWidth = 800;
                     if ($dstSize->getWidth() > $maxWidth) {
                         $dstSize = $dstSize->widen($maxWidth);
                     }
                     return $img
                         ->copy()
                         ->resize($dstSize);
                 },
             ]
         ]
    ];
}

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

public function actions()
{
    return [
       'galleryApi' => [
           'class' => GalleryManagerAction::class,
           // mappings between type names and model classes (should be the same as in behaviour)
           'types' => [
               'product' => Product::class
           ]
       ],
    ];
}

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

    echo sashsvamir\galleryManager\GalleryManager::widget([
        'model' => $model,
        'behaviorName' => 'galleryBehavior',
        'apiRoute' => 'product/galleryApi',
        'options' => [
            'class' => 'form-group',
        ],
    ]);

Done!

Now, you can use uploaded images from gallery like following:

foreach($model->getBehavior('galleryBehavior')->getImages() as $image) {
    echo Html::img($image->getUrl('medium'));
}

Options

Using non default table name for gallery images(default is {{%gallery_image}}):

1. Add migration that will create table you need
2. Change tableName property in behavior configuration
