Dear friends,

I'm accesing mails only through oulook express.
I cannot able to save the GIF files in my hard disk from
my outlook express.
By default it saves as a BMP file.
In BMP files the animation is not found in the images.
How can i save a GIF file from outlook express.Please help
me out.

Thanks in advance.
