Thanks for the feedback, everyone.

Since my interest is with inline images, placed with img_assist, in drupal 
4.7, I came up with this snippet which is working so far...

function custom_nodeapi(&$node, $op, $a3, $a4) {

  if ($op == 'view') {
    // For teasers, show thumbnails, not full images
    if ($a3) {
      //drupal_set_message("custom_nodeapi($op)" . dpr($node->teaser, 1));

      // modify the img tags inserted by img_assist
      $teaser = preg_replace('/<img src="([^"]*)\.([^\."]*)\.([^\."]*)" 
([^>]*) class="image ([^"]*)"([^>]*)>/',
                             '<img src="$1.thumbnail.$3" $4 class="image 
thumbnail" />',
      //drupal_set_message("new teaser: " . dpr($teaser, 1));
      $node->teaser = $teaser;

Will post the same to the drupal forum.
