Answer 1

you must implement a getWebPath method in your entity Image class (look at pre-requisites), something like:

protected function getUploadDir()
{
    return '/uploads';
}

public function getWebPath()
{
    return null === $this->path
        ? 'null'
        : $this->getUploadDir().'/'.$this->path;
}
