@ -656,6 +656,26 @@ See here the methods that you can override in your custom Images Pipeline:
.. versionadded:: 2.4
The *item* parameter.
.. method:: ImagesPipeline.thumb_path(self, request, thumb_id, response=None, info=None, *, item=None)
This method is called for every item of :setting:`IMAGES_THUMBS` per downloaded item. It returns the
thumbnail download path of the image originating from the specified
:class:`response <scrapy.http.Response>`.
In addition to ``response``, this method receives the original
:class:`request <scrapy.Request>`,
``thumb_id``,
:class:`info <scrapy.pipelines.media.MediaPipeline.SpiderInfo>` and
:class:`item <scrapy.Item>`.
You can override this method to customize the thumbnail download path of each image.
You can use the ``item`` to determine the file path based on some item
property.
By default the :meth:`thumb_path` method returns
``thumbs/<size name>/<request URL hash>.<extension>``.
.. method:: ImagesPipeline.get_media_requests(item, info)
Works the same way as :meth:`FilesPipeline.get_media_requests` method,
