Well, since yesterday, lots of people have been hacking on this. See
discussion here (yeah yeah, I'm linking approvingly to Dave Winer,
hell has frozen over, etc; let it go, this is good stuff):

Real iPhoto/.Mac-generated feed is here:

No answer for this yet.

item/link points directly to the photo. <description> contains an
escaped HTML representation of the same photo, with an <img> element
wrapped in an <a> element. No evidence of any <enclosure>s.

Apple has indeed invented yet another RSS namespace that provides
additional photo information.
xmlns:apple-wallpapers="http://www.apple.com/ilife/wallpapers";
On the channel level:
<apple-wallpapers:feedVersion>0.9</apple-wallpapers:feedVersion>
On the item level:
<apple-wallpapers:photoDate>2005-11-29T04:36:06</apple-wallpapers:photoDate>
<apple-wallpapers:cropDate>2006-01-11 16:42:26 -0800</apple-wallpapers:cropDate>

I love the discrepancy between photoDate (missing a timezone, so, you
know, it was taken on this date, plus or minus 24 hours) and cropDate
(space instead of "T" separator, but including a timezone) and
metadata/PhotoDate (no clue what format that is).
It wouldn't surprise me if there were additional possible children of
<apple-wallpapers:metadata>, based on different iPhoto settings.
Also, as pointed out in the above-linked discussions, the rest of the
feed doesn't validate. The Content-type is screwy, the date formats
are wrong, and there is no channel/guid element in RSS.

>From the above-linked discussions, I gather that the link is just an
http:// link to the RSS feed, but evidence suggests that Apple may be
doing some sort of user-agent sniffing. Some people get the feed,
while other people claim to get an HTML page explaining that their
client is unsupported. (I can't currently reproduce this error
message, so things may have already changed on the server side, or I
may be misunderstanding the initial reports.)

No answer yet.

No answer yet.
