New to Java

I currently have some java code that displays a moving gif file i.e. a gif file that has several images in it that are shown in a timed sequence and can give the illusion that the picture is moving if animated correctly.

Anyway I use
logo1 = new ImageIcon("magic.gif" );
to get the image and latter use a method that displays it.

My question is basically I was wondering if there is any other method I can use to slow the gif file down.

Otherwise I am going to have to edit the gif image itself by using some image manipulation software which I currently don�t have.

Any idea if this is possible.
Thanks
