Jim,

I don't know the answer to your dilemma but I have a piece of advice for your wife. Tell her that one should NEVER delete photos with the camera. The reason is that cameras (all cameras, I'm afraid even expensive full frame and medium format cameras) have a nasty habit of corrupting the other files and even DELETEING the other images if you try to delete any single image. Fortunately, this doesn't happen often but it DOES happen. If you want to delete an image, delete it with your computer and NOT with the camera itself.

Hope this info helps.

Mark
