fixed resize logic to avoid image lost

Preparations

In the index.php, after $application->Init();, place following code:

$upload_helper = $application->recallObject('kUploadHelper');
$upload_helper->resizeUploadedFile(FULL_PATH . IMAGES_PATH . '120x105.png', 'resize:120x120');
$upload_helper->resizeUploadedFile(FULL_PATH . IMAGES_PATH . '904x791.png', 'resize:120x120');

Testing

1. place attached file 120x105.png (dimensions: 120x105) to the /system/images/ folder
2. place attached file 904x791.png (dimensions: 904x791) to the /system/images/ folder
3. open website's Front-End
4. confirm that 120x105.png is in place and not changed it's size
5. confirm that 904x791.png is resized to 120x105 (if D370 is applied) or 121x106 (if D370 is not applied)
