Replace "Posted by"

How about removing the "Posted by" setting and turning this over to the theme settings? This not only reduces the settings, but allows other modules (e.g. Submitted By) to control the display in a way that the admin has more control over.

function theme_image_gallery_img($image, $size) {
  $width = $size['width'];
  // We'll add height to keep thumbnails lined up.
  $height = $size['height'] + 75;

  $content = '<li';
  if ($image->sticky) {
    $content .= ' class="sticky"';
  }
  $content .= " style='height : {$height}px; width : {$width}px;'>\n";
  $content .= l(image_display($image, IMAGE_THUMBNAIL), 'node/'. $image->nid, array('html' => TRUE));
  $content .= '<h3>'. l($image->title, 'node/'. $image->nid) .'</h3>';
//  if (variable_get('image_gallery_node_info', 0)) {
//    $content .= '<div class="author">'. t('Posted by: !name', array('!name' => theme('username', $image))) ."</div>\n";
    if (theme_get_setting('toggle_node_info_'. $image->type)) {
      $content .= '<div class="author">'. theme('node_submitted', $image) ."</div>\n";
    }
//    if ($image->created > 0) {
//      $content .= '<div class="date">'. format_date($image->created) ."</div>\n";
//    }
//  }
  $content .= "</li>\n";

  return $content;
}
