.zip Files

I've added these zip files, maybe it will help some of you people on slower connection to download them...  at least you don't have to click on one .jpg and have to wait like five minutes just to read it.  This way you can select an article, go do something then come back and it'll be ready.  WinZip wasn't able to reduce these .jpg's much.
