Image attached to a node in a block

Hi there,

I had previously asked a question about having an image that was attached to a node appear in a block. The solution that David provided worked fine but... I finally decided to develop the website with Drupal 5.x and the trick does not work anymore.

The code provided was:

  $node = node_load(arg(1));
  if ($node->iid) {
    $image = node_load($node->iid);
    print l(image_display($image, 'image_node'), "node/$node->iid", array(), NULL, NULL, FALSE, TRUE);
  }

When I use that as a block with Drupal 5.x, the image displays fine when there is an image attached to a node but I get an ugly SQL error on nodes that have no image attached.

Here is the error:

* warning: Invalid argument supplied for foreach() in c:\program files\easyphp1-8\www\modules\node\node.module on line 504.
    * warning: implode(): Bad arguments. in c:\program files\easyphp1-8\www\modules\node\node.module on line 508.
    * user warning: Erreur de syntaxe pr�s de '' � la ligne 1 query: node_load SELECT n.nid, n.vid, n.type, n.status, n.created, n.changed, n.comment, n.promote, n.sticky, r.timestamp AS revision_timestamp, r.title, r.body, r.teaser, r.log, r.format, u.uid, u.name, u.picture, u.data FROM node n INNER JOIN users u ON u.uid = n.uid INNER JOIN node_revisions r ON r.vid = n.vid WHERE in c:\program files\easyphp1-8\www\includes\database.mysql.inc on line 172.

This looks like the error I had previously in Drupal 4.7.x without the "if" statement, which makes me think that the statement does not work with the new version anymore.

Can anyone help?

Thanks a lot!
