I don't think you understand what this app is trying to do.

To kojacker, this sounds like a nice app. It would be good to have a GUI to pick a person from your contacts list to pick up the name and image, although you also need a way to type that info in manually for people not in your contacts.

For the time being, I would be happier for the app to not write into the call log. If you ever do get to that point, I would suggest making it optional.
