I'm having a recipe for the german journal "Tagespost", it's this one:

#!/usr/bin/env python
# vim:fileencoding=utf-8
from __future__ import unicode_literals, division, absolute_import, print_function
__license__ = 'GPL v3'
__copyright__ = '2020, Pat Stapleton <pat.stapleton at gmail.com>'

from calibre.web.feeds.news import BasicNewsRecipe


class AdvancedUserRecipe1589629735(BasicNewsRecipe):
    title          = 'Tagespost'
    language       = 'de'
    __author__     = 'Pat Stapleton'
    description = ('Die Tagespost trägt den Untertitel Wochenzeitung für Politik, Gesellschaft'
        ' und Kultur und ist eine überregionale, wöchentlich im Johann Wilhelm Naumann Verlag in Würzburg erscheinende Zeitung.')
    oldest_article = 7
    max_articles_per_feed = 100
    auto_cleanup   = True
    use_embedded_content = False

    feeds          = [
        ('Tagespost', 'https://www.die-tagespost.de/storage/rss/rss/die-tagespost-komplett.xml'),
    ]
    extra_css = 'td.textb {font-size: medium;} * { text-align: justify !important; text-decoration: none !important}'
    remove_attributes = ['href']

calibre_most_common_ua = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36'

Everything works well, so far. But when I began to make use of it, some two years ago, there were lots of images downloaded, too. In the current of time, the images became fewer, eventually there has been downloaded only one image, and now, for a few months, none at all.
I'm quite satisfied with the recipe, so my remark is more a question out of interest than a request for support: Are there technical reasons for this behaviour, or am I doing something wrong? - In the current of time, I admit, the content of the journal has considerably augmented: from about 100 pages (on my e-reader) up to 200 and more.

auto_cleanup = True in recipe.
https://manual.calibre-ebook.com/new...Recipe.cleanup

you can use keep_only_tags & remove_tags to keep only those html tags you think has text and images and remove unnecessary tags to fix it.

@unkn0wn: Thank you, so far! auto_cleanup = True is already in the recipe. Do you mean that I have to change that?
Sorry, I'm no technic at all!

Yes auto_cleanup is True, which does its own thing, it might ignore images or other tags. You can remove that and use the keep_only_tags to fix it.

I thought you didn't want support. So I pointed you towards documentation.

Oh, I should well enjoy having my images back!
So, as I understand, I should replace:

auto_cleanup   = True

by:

keep_only_tags

I'll give it a try!

Edit: I tried, but there comes an error message: "keep_only_tags should be defined".
Would it be correct to write:

keep_only_tags = True

?
Sorry again for my ignorance!

Wonderful! Not only that the images appear again, but the entire layout seems prettier!
So great! Thank you!
