What you could do is edit file includes/class_bbcode.php and add the hook call. You would find this (around line 1993):

	return '<img src="' .  $link . '" border="0" alt="" />';

and change it to:

	$retval = '<img src="' .  $link . '" border="0" alt="" />';

	($hook = vBulletinHook::fetch_hook('bbcode_img_match')) ? eval($hook) : false;

	return $retval;

and then to get that hook to appear in the list of hooks when creating a plugin, you could create a file called includes/xml/hooks_added.xml with this content:

<?xml version="1.0" encoding="ISO-8859-1"?>

<hooks>
	<hooktype type="general">
		<hook>bbcode_img_match</hook>
	</hooktype>
</hooks>

Or alternatively you could just edit includes/bbcode.php and insert the actual mod code instead of a hook call.
