Hi.

You may find usefull to look at how some other recipes are written. There is 
the ParseArgs() pmwiki function that will help you a lot, like this:


Markup("jPhoto", 'inline'
     "/\\(:jp(l|r|c) (.+?):\\)/se",
     "Keep(jpFixMarkup('$1',PSS('$2')))"
);

function jpFixMarkup( $type, $args)
{

	$opt = ParseArgs($args);
	
	# $opt['src'] is now your src= value
	# $opt['pop'] is now your pop= value,
		# to get the parts, use:
	list($path, $w1, $w2) = explode('|', $opt['pop']);
	# $opt['capt'] is now your capt= value
	
	return Keep("<pre>".print_r($opt, 1)."</pre>");

}


You may see for example how the Thumblist recipe is written. It accepts many 
arguments in the markup; it is quite complex but may be of some help, for you 
to write your own recipe. (Coincidently, it also does thumbnails linking to 
the originals.)

If you have any questions about this code, I'll be happy to help.

P.S. Remove the last ?> from your code, it is not needed, but any eventual 
newline/whitespace after it may break your layout with a PHP warning.
