Create snapshots with a timestamp (Snapshot_2023-11-20-074526.jpg) filename rather than a serial (Snapshot_002.jpg) name.
Second Life has long taken screenshots and saved them with a simple number suffix: _XXX.png/jpg. This makes organizing images tedious, as the filename doesn't necessarily match the order/time in which the image was captured.
There are also two formats, with the 360 snapshot feature including a bunch of ancillary information:
  1. Standard Snapshot - Snapshot_001.jpg
  2. 360 Snapshots - sl360_Linden_Lab_HQ_1_4096x2048_128_20231120_074526.jpg
There could be more consistency here, with the same pattern used for both. Or, if it's simpler: just add a timestamp to standard snapshots.
