✅

You can use a SerializerMethodField to return the list of associated images:

class PackageGalleryDetailSerializer(serializers.ModelSerializer):
    images = serializers.SerializerMethodField()    

    class Meta:
        model = Package
        fields = '__all__'

    def get_images(self, package):
        return [
            # Change this to meet your need e.g. `gallery.image.url`
            gallery.image.name
            for gallery in package.gallery.all()
        ]

Also, the related_name from PackageGallery to Package should be named e.g. galleries to have a better notion of the relationship as it’s a many-to-one.

And you can drop the get_queryset method from ListPackageGallery as we don’t need any filtering.
