+This is a simple plugin to convert all site-relative links to page-relative links (converts /foo into ../../../foo or similar). It works as a postprocessing filter, allowing it to work on mdwn, wiki, html, rst and any other format that produces html. The code is available here:
+
+	#!/usr/bin/perl
+	# quick HTML abs2rel link hack by Paul Wise
+	package IkiWiki::Plugin::siterel2pagerel;
+
+	use warnings;
+	use strict;
+	use IkiWiki 2.00;
+
+	sub import { #{{{
+	        hook(type => "sanitize", id => "siterel2pagerel", call => \&siterel2pagerel);
+	} # }}}
+
+	sub siterel2pagerel (@) { #{{{
+	        my %params=@_;
+	        my $baseurl=IkiWiki::baseurl($params{page});
+	        my $content=$params{content};
+	        $content=~s/(<a(?:\s+(?:class|id)\s*="?\w+"?)?)\s+href=\s*"\/([^"]*)"/$1 href="$baseurl$2"/mig;
+	        $content=~s/(<img(?:\s+(?:class|id|width|height)\s*="?\w+"?)*)\s+src=\s*"\/([^"]*)"/$1 src="$baseurl$2"/mig;
+	        # FIXME: do <script and everything else that can have URLs in it
+	        return $content;
+	} # }}}
