Some more thoughts, because of this other topic: What I essentially would like to ensure is that every file and every episode post have a cover image. Which should be the podcast’s logo, whenever I don’t define a special episode cover. I thought this can be achieved by configuring the podcast cover in both the Podlove’s Podcast Setting > Cover Art URL and Auphonic’s Presets > Cover Image. In case a special cover is used, I replace the Cover Image in Auphonic, and set it as an Output File. So far so good, or am I mistakenly assuming that Auphonic writes it into the audio files, format permitting?
If not, the issue I described in the orginal post still seems like a bug to me. In which scenario would anyone want use a temporary image file from https://auphonic.com/api/download/... as an episode cover? In case a podcast needs only few special episode covers, this even gets in the way of the main workflow: not changing any default, so that Podlove can fall back to the podcast cover.
Besides correcting this manually each time, or letting the same image be copied around over and over, I could imagine that either the PPP implements some kind of ignore rule for that temporary URL, or Auphonic doesn’t serve it.
