The Illinois DNR offers digital orthoquads of most of the state for free download.  Below is the address for anyone interested.  I'll warn you, the files are large (2-3Mb) so be prepared for a long download if you don't have high speed access.  There is also a link to a free viewer that you will need to view the files.

It appears that the images are the same ones used by terraserver but you can zoom in a lot closer and it has a realtime pan so you can pan as much or as little as you need to.
