Of course, myAlbum-P supports PNG.
Only I don't know MIME type of image/png.
(Normally, the MIME type of PNG is image/x-png)
All you have to do is add "image/png" into the end of include/read_configs.php like this:
$array_allowed_mimetypes = array("image/gif","image/pjpeg","image/jpeg","image/x-png","image/png") ;
I know it is a weakness of myAlbum-P that MIME type is not editable from control pannel.
It should be improved.
