This method works fine for me:
$index = 0;
foreach ($node->field_image as $image) { // if your image field is named 'image'
$index++;
$filepath = $image['filepath'];
$alt = $image['alt'];
$title = $image['title'];
if ($index == 1) {
// first image large
print '<a href="/'.$filepath.'" rel="'.$node->type.'-'.$node->nid.'" title="'.$alt.'" class="thickbox">'.theme('imagecache', 'large', $filepath, $alt, $title).'</a>';
} else {
// remaining images smaller
print '<a href="/'.$filepath.'" rel="'.$node->type.'-'.$node->nid.'" title="'.$alt.'" class="thickbox">'.theme('imagecache', 'small', $filepath, $alt, $title).'</a>';
}
}You just need to set up two imagecache presets: one for the 'large' and one for the 'small' image.
