[X-Unix] Compressing files

[Mark Philip]

Hi all,
I've got a directory called Timothy Ng, which contains lots of JPEG 
images. I wish to compress these images into a ZIP file, put the ZIP 
file into another directory (say Desktop) and then email this file to a 
user who is running Windows XP. I used to do this a while ago but have 
forgotten how to do this using TAR. Can anyone help me out?

Much appreciated...
