I publish a podcast feed from my WordPress.org blog using Blubrry PowerPress. Recently I had my podcast added to Stitcher, and I found that, when they pull the feed in, the first thing you see in the episode description is the pathname of a JPG file that I used to illustrate the blog post. I asked them how I could fix that, but they said the only way was to remove the image.
I'm sure there are more satisfactory fixes. Any ideas?
