My podcast is at iTunes and seven other podfeed hosts. I have no trouble with my podcast image (or iTunes image). My question is about item images. At iTunes, I have to open each enclosure in iTunes, go to Get Info, and load the image into the Artwork tab, before uploading. For blubrry.com, I have to code it this way:
<description><![CDATA[<img src="URL OF YOUR IMAGE">
Text of your description]]></description>
However, I am unable to figure out how to code my item images so they show at podcast.com, podfeed.net, digitalpodcast.com, and other podfeed hosts.
