Deploy Image - disk image missing

I'm trying to deploy an image that I made yesterday.  It is a sysprepped image of Windows 7.  When I create the task, and I have to select the image, it says no items found.  I've made two images and neither show up.  What do I need to do to get these images to appear so I can select them?

As a side question, I have a NAS that I like to store my images to in previous versions of Altiris.  Can I force the server to create my images and save them to the NAS?
