Hi Louie,
MobiOne designs are saved as HTML5 webapps that run and behave similar to native apps. We are working on a native app generation solution now.
Regarding missing images, can you tell be a bit more? When a mobione design is exported all images referenced in a design should be copied to an /images subdirectory.
Example:
/mymobileapp
/mymobileapp/images <- your images copied here
