I finally figured out how to make a ssi function for displaying a post that includes attachments. It's based on grab a single message with ssi (http://custom.simplemachines.org/mods/index.php?mod=18), to which I added the attachment stuff I found in other topics. It works, but the attachment stuff is very basic atm and only works for pictures (which is what I personally need it for).
Things I would like to add include making the thumbnail clickable after which the picture stretches to its full size (no popup). Can anyone help with that?
Here's the code:
//////////////////////////////
// Return a single post //
/////////////////////////////
function ssi_grabMessage($message_id = null, $output_method = 'echo')
{
global $scripturl, $db_prefix, $txt, $settings, $modSettings, $context, $attachments;
loadLanguage('Stats');
if ($message_id !== null) $message_id = (int) $message_id;
elseif (isset($_GET['ID_MSG'])) $message_id = (int) $_GET['ID_MSG'];
else die("Geen message id ingevoerd");
// This is needed for loadAttachmentContext()
include_once('Sources/Display.php');
// Fetch attachments.
if (!empty($modSettings['attachmentEnable']) && allowedTo('view_attachments'))
{
$request = db_query("
SELECT
a.ID_ATTACH, a.ID_MSG, a.filename, IFNULL(a.size, 0) AS filesize, a.downloads,
a.width, a.height" . (empty($modSettings['attachmentShowImages']) || empty($modSettings['attachmentThumbnails']) ? '' : ",
IFNULL(thumb.ID_ATTACH, 0) AS ID_THUMB, thumb.width AS thumb_width, thumb.height AS thumb_height") . "

{

mysql_free_result($request);
// This is better than sorting it with the query...
ksort($temp);

$attachments[$row['ID_MSG']][] = $row;
