Chuck, That is what an image restore does. It will take your image and replace whatever is on the partition with the image. That's assuming the image was successfully created.
If I understand your most recent post, you created an image of your OS (C drive) partition at some point in time. You then deleted all partitions on your PC and attempted to restore from your image. When you did, OO was reinstalled by the image. If this is correct, then my comment is that the image included OO and did as it is supposed to do.
I DO NOT believe you can mount the image and delete parts of the image before you restore that image to your HD. It's all or none. To do what you want you would have to restore your HD using your original image, then uninstall whatever apps you do not want on the image, then recreate a new image to use for future restores.
My feeling is that recreating images whenever any change takes place on your PC is a good thing. This way your PC image will be up to date so the restore is also up to date. That way the total restore is much quicker.
I hope I have understood your post and answered your question.

Note: When you deleted your partitions, did you then combine all previous partitions into one partition that included all the space on your HD? I think you did, but am not sure. If not use any partitioning app (I use
Partition Wizard) for this chore.
