Photo credits

27 photographs · used only on share cards · public domain or CC0

Every photograph used on Question Vault’s share images is public domain or CC0, so no attribution is required. Crediting the photographers anyway seemed like the decent thing to do.

The pages themselves carry no photography. These images appear only on the cards generated for shared links, printed as a single blue-ink duotone, so they may look nothing like the originals linked below.
