Why doesn't my podcast cover art show in store but appears in iTunes library after I subscribe?

Great, that explains it. We had moved the image to a new URL and actually updated the original feed that we input into Feedburner with that URL ... but we also had Feedburner Smartcast turned on which creates its own iTunes tags and overrides any that may already be in the feed, and the image URL in Smartcast there was the old one.

In any case, we not only updated Feedcast Smartcast with the correct image URL, but we also put a copy of the image at the old URL so that even the URL presently used by iTunes should work.

Any idea how long it takes for the store to update the cover art? Anything we can do to expedite it?

Thanks!

Great, we have a new file name. All URLs both old and new are valid, so any cached references, etc. should resolve. Thanks for the quick help!
