My response is pretty much directly from the Laravel Eloquent Docs, and is very basic.

class Image extends Eloquent {

    public function imageable()
    {
        return $this->morphTo();
    }

}

class Staff extends Eloquent {

    public function images()
    {
       return $this->morphMany('Image', 'imageable');
    }

}

class Order extends Eloquent {

    public function images()
    {
       return $this->morphMany('Image', 'imageable');
    }

}

add the following to your images schema

$table->morphs('taggable');

now to add an image for a job, for example:

$idOfJob = 1;
$image = Image::create(['imageable_id' => $idOfJob, 'imageable_type'=>'Job', 'title'=>'title here', 'path' => 'path here']);
