[TYPO3] default value of imageorient

[Stano Paška]

Hi.
I need set default value "imageorient" for every new content type "image" to value 2.

I think it can be done with page TSconfig, but I don't know how.

I found default value 8 (below center) defined in typo3/sysext/cms/tbl_tt_content.php:
		'imageorient' => Array (
			'label' => 'LLL:EXT:cms/locallang_ttc.php:imageorient',
			'config' => Array (
				'type' => 'select',
				'items' => Array (
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.0', 0, 'selicons/above_center.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.1', 1, 'selicons/above_right.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.2', 2, 'selicons/above_left.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.3', 8, 'selicons/below_center.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.4', 9, 'selicons/below_right.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.5', 10, 'selicons/below_left.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.6', 17, 'selicons/intext_right.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.7', 18, 'selicons/intext_left.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.8', '--div--'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.9', 25, 'selicons/intext_right_nowrap.gif'),
					Array('LLL:EXT:cms/locallang_ttc.php:imageorient.I.10', 26, 'selicons/intext_left_nowrap.gif')
				),
				'selicon_cols' => 6,
				'default' => '8',
				'iconsInOptionTags' => 1,
			)

Can it be redefined for image with 2 and for textpic with 10?

Thanks for answers.

Stano.
