Have you guys checked out
www.keyhole.com ? Its was recently purshased by google... however ive been using it for awhile. Pretty much a virtual globe that you can move around with your mouse zoom in zoom out... and it contains color satellite images of just about every major city and the surrounding areas in the world. If you guys want to PM me your address or something you want to see, ill post an example of it. I can spend hours on this thing. If enough people use it we can start posting actual hyperlinks that open up the globe and take you to the locatoin.
Go download the demo and youll see what i mean.
