$EnableUpload: The upload.php script is automatically included from stdconfig.php if the $EnableUpload variable is true in config.php. Note that one may still need to set an upload password before users can upload (see UploadsAdmin).
$UploadDir: The directory where uploads are to be stored. Defaults to uploads/ in the pmwiki directory, but can be set to any location on the server. This directory must be writable by the webserver process if uploading is to occur.
$UploadUrlFmt: The url of the directory given by $UploadDir.
$UploadPrefixFmt: Sets the prefix for uploaded files to allow attachments to be organized other than by groups. Defaults to '/$Group' (uploads are organized per-group), but can be set to other values for sitewide or per-page attachments.

    $UploadPrefixFmt = '/$FullName';    # per-page attachments
    $UploadPrefixFmt = '';              # sitewide attachments

$EnableDirectDownload: When set to 1 (the default), links to attachments bypass PmWiki and come directly from the webserver. Setting $EnableDirectDownload=0; causes requests for attachments to be obtained via ?action=download. This allows PmWiki to protect attachments using a page's read permissions, but also increases the load on the server.
