two questions really regarding the metadata ['relation']['firstimage']
1. for an OpenGraph plugin i'm looking at generating the uri to this
image using:
...
global $ID;
$rel = p_get_metadata($ID,'relation',true);
$img = $rel['firstimage'];
if(!empty($img)) {
return DOKU_URL .'lib/exe/fetch.php?media='.$img;
...
which seems to work OK, but I'm curious if there is a better way to
generate the canonical url to the image, especially when the wiki uses
url rewriting. Should I be using ml()? eg. ml($img, array(), true,
'&', true)
running example at

full code:

2. I have a (different, not related to the opengraph) syntax plugin
that puts an image (a map actually) on a page and does not update this
metadata, I'm now wondering whether it should (taking into account
existing images etc..)?
Thanx, Mark
