shadlaws 536bdaa4db #1967 - Improve how graphics::generate handles missing/bad images.
- Made missing_photo match the image format (jpg, png, etc.).
- Swapped missing_photo.png for missing_photo.jpg since it's likely to require less conversion to match.
- Improved error messages to user when things go wrong.
- Ensured that missing image placeholders are always copied when there's an error.
- Ensured we don't mistake no file output for a correct file output (delete target before attempt).
- Restructured graphics::generate a bit to work better with above changes.
- Added unit tests for graphics::generate.
