במידה ואתם רוצים לעצב את הרשימה של הקבצים המצורפים כמו זה

אתם יכולים לבצע Override ל upload_attachments
יצרו מחיצה icons תחת ה theme, פתחו את ה tar המצורף לשם, הוסיפו icons נוספים לפי הצורך

הוסיפו את קטע הקוד הבא ל template.php

function phptemplate_upload_attachments($files) {
$header = array(t('Attachment'), t('לחץ להורדה'));
$rows = array();
foreach ($files as $file) {
$file = (object)$file;
if ($file->list && !$file->remove) {
// Generate valid URL for both existing attachments and preview of new attachments (these have 'upload' in fid)
$href = file_create_url((strpos($file->fid, 'upload') === FALSE ? $file->filepath : file_create_filename($file->filename, file_create_path())));
$text = $file->description ? $file->description : $file->filename;
$rows[] = array(theme('file_icon', $file) ,l($text, $href,array("title" => " גודל הקובץ :" . format_size($file->filesize))));
}
}
if (count($rows)) {
return theme('table', $header, $rows, array('id' => 'attachments'));
}
}
