thanx for the alternative but iChat will not work on Leopard also, or am i wrong?
Oh, it definitely does. iChat was introduced in around 2003 or so, way before Leopard. Macs still technically have it, although it became intertwined with 'Messages' as of Mountain Lion. MacOSX comes with iChat, and I am running it on my Leopard machine as I type this.

This is what i was saying about ichat not working in Leopard
That's OS 10.6 Snow Leopard, not Leopard. Also, that must have been some sort of error/mishap. iChat wouldn't NOT work with a certain MacOSX version; it's Apple's own product for MacOSX. I have iChat on my Panther machines, Tiger machines, Leopard machines, and Snow Leopard machine. I'd really recommend it though; it was the first time anyone had ever gotten video chat, audio chat, etc. to just simply work!
Even today, things like the AIM application have a very primitive video chatting option. Many clients today still don't even have the option because it's difficult to do. iChat implements the usefulness of AIM messaging with iChat and its awesome features. You can send images so that they appear right in the window, w/o some URL; you can share your friend's screen (and be able to control the mouse) or vice versa; you can even send files over it! Admittedly, I used to screen share with my friend so I could play Sims 3 from his computer, as he watched xD
