show bookmark pictures.
Some podcasts using pictures for their bookmarks eg. Lage der Nation. https://feeds.lagedernation.org/feeds/ldn-mp3.xml Pocket Casts already shows them. It would be great if you could add support for this, too.
Podcats Addict has been supporting bookmarks for the past few years. Urls and artwork are supported as well
There may be confusion here between the terms "bookmark" and "chapter". What is meant is chapter artwork, which apparently can change during chapters.
