We have changed the way of how images are saved with 3.3, because if they were included to the executable it could get very huge if you are working with big/much images, so it is not the recommended way.
Does the copy of the file make big troubles?
If yes, I could add an issue and we would discuss if we should add some kind of an option how a user can include that file.
The repository is already included in the exe file, but the images aren't saved to the repository file, they are stored in the Image Repository file.
