The corresponding `*_1688.jpg` reconstruction images, the `*_overlay.jpg` alignment
images, and the combined slider comparisons made from these pairs are also distributed
under **CC BY-SA 4.0**. Attribution: **Ayutthaya 1688 reconstruction project**, with the
photographer credit above wherever a comparison includes their photograph or derived edges.
The overlays trace photographic edges over a code-rendered reconstruction to check alignment;
they are adaptations, not independent photographs. The slider reveals two complete images;
it does not claim that the reconstructed architecture is established fact.

You may copy and adapt these images, including commercially, subject to attribution,
an indication of changes, a licence link, and ShareAlike for adaptations. No additional
restrictions or endorsement are implied. This image licence does not replace the MIT
notices for the engine or the ODbL terms for the map database.
