So, finally succeeded:
PHP код:
require_once(PATH_t3lib . "class.t3lib_stdgraphic.php");
require_once(PATH_tslib . "class.tslib_gifbuilder.php");
require_once(PATH_t3lib.'class.t3lib_tstemplate.php');
require_once(PATH_t3lib.'class.t3lib_page.php');
require_once(PATH_tslib.'class.tslib_content.php');
$TSFEclassName = t3lib_div::makeInstanceClassName('tslib_fe');
$id = isset($HTTP_GET_VARS['id'])?$HTTP_GET_VARS['id']:0;
$GLOBALS['TSFE'] = new $TSFEclassName($TYPO3_CONF_VARS, $id, '0', 1, '', '','','');
$GLOBALS['TSFE']->initFEuser();
$GLOBALS['TSFE']->fetch_the_id();
$GLOBALS['TSFE']->initTemplate();
$GLOBALS['TSFE']->getConfigArray();
$myCobj = t3lib_div::makeInstance('tslib_cObj');
echo $myCobj->IMAGE($imgTS);
Have no idea how it will be faster than regular plugin in normal page.
