He means the difference between <itunes:link rel="image" href="..."/>,
<itunes:image href="..."/>, <itunes:image>...</itunes:image>, and
whatever other variations people dreamed up while both your spec and
your app were changing every day in contradictory ways.
It's a valid question, and probably the #1 point of confusion for
podcasters.
I completely agree its a valid question, I'm just saying *I* don't
understand it. :-)
Your answer helps some, thanks.
The itunes:image tag is only
defined for RSS (the use in Atom is unsupported at this time).
And yet despite being unsupported and undocumented, embedding in Atom
works just fine (as long as you don't care about being listed in the
podcasting directory, grr).
I appreciate that it can be done (sorta), but as you can see we're
having enough trouble getting the *RSS* part documented. :-)
Just to be 100% clear on the question, you are asking:
"What is the proper syntax for the "image" tag in iTunes RSS?"
That question I will look into and try to get an answer. It is good
to know that is the #1 question.
