"Installation Complete" photograph submission is something that cnArcher may be able to support in a future release. That is, the installer could be required to take photographs of the final install and submit them before "completing" the job.
It is not supported in the first release of cnArcher (coming in a few weeks), but the idea sounds great and useful. I will see what kind of effort it will be to incorporate this in a future release of the app. Please kudo this if you might find it useful.
