Not yet, there is already a patch in our issues tracker to read GrayScale PNG image (http://bugs.libgd.org/?do=details&task_id=88) but I did not yet manage to add write support for PNG grayscale images. The plan is to first add a grayscale internal format (8, 16 or 32, with alpha or not) and then allow one to save it as a grayscale image (png, tiff, tga for ex.). Alternatively you can use the grayscale conversion function to convert the image to a faked grayscale image and save it as a rgba PNG. It is not the perfect solution but it is visually correct.
