Try this in what file ???
please let me know.
Because I saw in config.php those command already there. so..what's the new ???

// Uncomment the following line if you experience problems with the image
// upload. Debug messages will be added to the error.log file.
// $_CONF['debug_image_upload'] = true;

As it says there: Uncomment the line, i.e. remove the // in front of it.

bye, Dirk
