Does anyone know the format (size? color? file ext?) for the images that represent locations and contacts on the Z1?

 

Was thinking it would be fun to upload fav pics of friends so they appear when I'm near their place or when they call.

 

I know there's a grey'd out "import" option. I assume the process is similar to uploading a background image (files + 100meg dummy) but just thought I'd ping for details.

 

Also, what about sounds? The squeaking bed works great for my girlfriends place but I can think of other great applications for this.

 

Thanks all!
