with the following at line number 512 or around it in Image_lib.php. it maintains transparency for both gif and png images. note the
imagefilledrectangle() replacing
imagefill(). with imagefill() the transparent part becomes black. but imagefilledrectangle() maintains transparency.
Code:

$cr_img_type = $proprts['image_type'];
//$cr_width = $proprts['width'];
