How to detect an image type with GD

Hi.

I want to load an image with GD, but I must know which type is each one
in order to:
my $srcimage = GD::Image->newFromGif("foo.gif");
my $srcimage = GD::Image->newFromJpeg("foo.jpg");
....

How can I detect it? Thank you very much.

Do not. Let GD detect it.

Hope this helps,
