How to override pictures

[paul@gh]

Hello !

We need to display a default "No Picture" image when a variant has no image on its own instead of displaying ALL the product images.

In order to achieve this we needed to change the behavior of the ImageRetriever class.

Replacing

return (0 === count($filteredImages)) ? $images : $filteredImages;

By

return (0 === count($filteredImages)) ? [
            $this->getNoPictureImage($language)
        ] : $filteredImages;

As we do not want to modify Core code base, we had to

1. Extends the ImageRetriever class
2. Override the ProductPresenterFactoryCode class in order to instantiate our ImageRetriever class instead of the core one.

It is working as intended for us.

Pros

No modification of the Core classes

Cons

A lot of overridden code.
Even if we extends the core classes (ProductPresenterFactoryCore and ImageRetriever),  we had to override every properties and methods as they are not intended to be extended (private property, ...).

In my opinion this is really bad. We should be able to alter core behavior without relying on so much code override.
