[TYPO3-dev] cObj->IMAGE in BE doesn't work

[Georg Ringer]

Hello,

I want to use a cObj in a BE-module and I only get the following error if I 
use instance: Fatal error: Call to a member function on a non-object in 
/typo3_src-4.0.2/typo3/sysext/cms/tslib/class.tslib_content.php on line 4603

I only get the error with an cObj->IMAGE, with cObj->TEXT everything is 
fine.

Some looks at the core:
tslib_content.php #4603: $theImage = 
$GLOBALS['TSFE']->tmpl->getFileName($file);
=> Problem because $GLOBALS['TSFE']->tmpl->getFileName() doesn't work

my code:
// -----------------------
require_once(PATH_site.'tslib/class.tslib_content.php');
$cObjLocal = t3lib_div::makeInstance("tslib_cObj");
$file = 'uploads/tx_rgtemplatemaker/layout011.gif';
$imgTSConfig = Array();
$imgTSConfig['file'] = $file;
$imgTSConfig['file.']['maxW'] = 10;
$imgTSConfig['file.']['maxH'] = 20;

echo $cObjLocal->IMAGE($imgTSConfig);
//-----------------

So 2 questions:
- Where is my problem or
- How do I get cObj->IMAGE in a BE-module?

many thanks for reading, more thanks for answering ;)
