Immediately after submitting my feed to the iTunes store, I realized that I failed to create an image for it. I promptly changed it in podPress, but when the podcast appeared on the store it still had the old image. I assumed it just took some time, so I waited. When nothing changed, I checked the rss feed itself and noticed that it was still linking to the Mighty Mouse picture. I am unsure how to proceed.
Here is a link to the feed itself, showing that the iTunes image is still the "Powered by podPress" jpeg:
