move image into Acronis Secure Zone?

How can I move an already created Acronis disc image (*.tib) into the Acronis Secure Zone? I am using Acronis True Image Personal v.8 and Acronis Disk Director v.10 on WinXP.

Here is the original problem. I have done it successfully a number of times before but, for some reason, this time when I try to restore a partition image I get an error "Not enough memory". When I check my partitions, one of the other partitions is now marked unallocated (which is fine because I can recover it) and of course the one I wanted to recover has not been recovered.

So I thought I would try to restore through the Startup Recovery Manager. However, I can't figure out how to get the image I previously created into the Secure Zone.

Help?
