ah, thats very good – try to change the content of the saveMetadata-function (beginning on line 209 in save.php)
$fullFilePath = trailingslashit($currentFilePathInfo['dirname']) . $currentFilePathInfo['basename'];
$fileInformations = wp_check_filetype($fullFilePath);
$newValues = array();
$newValues['file'] = $currentFilePathInfo['basename'];
$newValues['width'] = intval($croppedWidth);
$newValues['height'] = intval($croppedHeight);
$newValues['mime-type'] = $fileInformations['type'];
$oldValues = array();
if(empty($imageMetadata['sizes'])) {
$imageMetadata['sizes'] = array();
}
if(!empty($imageMetadata['sizes'][$imageSizeName])) {
$oldValues = $imageMetadata['sizes'][$imageSizeName];
}
$imageMetadata['sizes'][$imageSizeName] = array_merge($oldValues,$newValues);
do_action('crop_thumbnails_after_save_new_thumb', $fullFilePath, $imageSizeName, $imageMetadata['sizes'][$imageSizeName] );
return $imageMetadata;
