Call to a member function getImages() on null

[bogdan-baerov]

Hello, after lots of time at last I can upload and see the images at least, but when I try to use:
foreach($model->getBehavior('galleryBehavior')->getImages() as $image) {
echo Html::img($image->getUrl('medium'));
}
I get that error, no idea what to do, please help

$model in code about should be active record where you attached gallery behaviour, but not GalleryImage.

Oh, I understand, I have a Product model with that behaviour, so I'll just change that, thank you very much, oh and another tip, please...make the documentation more explicit, it's really a lil pain in the ass
