However, there is a problem: because of the way that cx_Freeze bundles our Python module in a compressed archive, accessing file paths inside the module is problematic.
Our images module presents such a problem: it contains PNG files that our application accesses by calculating a relative path from its __init__.py file. To address the issue, the PNG files will need to be relocated to a directory outside the package during the build process. Our code will then have to find them in the new location when it's been frozen, and in the original location when not.
