How to find an IOS image with CCME of version XY and vice versa?

During the CZ&SK NetAcad conference some guys asked me how could they find which IOS contains the Cisco Unified Communications Manager Express (formerly Cisco Call Manager Express). The answer is quite easy, you can use Cisco Feature Navigator web page. Click on the "Search by feature", then select "Call Manager Express" in version that you want and click on "Add" and "Continue". Then select your "Hardware plaform" and there you are :) You will get a list of IOS images for your HW platform which contains CCME.
If you have an IOS image, and want to know what features are supported in your IOS image then on the Feature Navagator click on the "Search by image".
Enjoy :)
