No, I was not. I'm just experimenting...

plugin:dil uses 'inc/HTTPClient.php' ;-) ...
Obviously I took "Hint: use the SimplePie library shipped with DokuWiki
to parse the feed." from your last mail wrong :-( And from the
plugin:dil page I learned that I may not use
http://feeds.feedburner.com/DilbertDailyStrip but
http://feedproxy.google.com/DilbertDailyStrip as URL for the feed (since
feedburner refuses feeds to user agent 'SimplePie', that's why I
introduced another user agent string).

OK. I'll work along
<http://simplepie.org/wiki/tutorial/grab_custom_tags_or_attributes> -
this should work since FeedParser.php is a wrapper around SimplePie.

I see that I have to append '&.gif?' (or similar), if the picture file
extension is not the last part of the URL. Frank Thommen had the same
problem just a week ago on this list :-(

Yes, it is expensive, I noticed the long runtime. And again I learn a
new internal of DW... plugin:dil puzzles together the link manually,
that's what I tried with my last attempt, but I want to be more flexible...
So it would be
$renderer->externalmedia($src,$title,$align,$width,$height,$cache) where
$title is constructed as described on
<http://www.dokuwiki.org/devel:parser> at function externalmedialink
(which is an empty function in renderer.php and does not occur in
xhtml.php).
@Andi W.: yes, normally I do not "believe" other web sites. I will use
hsc(), it has less letters ;-)
Thank you! I'll try soon!

Werner
