images | string[] | yes | — | Up to 10 publicly-fetchable HTTPS URLs. First is primary; rest are auxiliary. |
size | enum | no | auto | auto (preserve input), 1024_1024 (1:1), 1024_1536 (2:3 portrait), 1536_1024 (3:2 landscape). |
size=auto preserves the input ratio — strongly recommended unless the edit explicitly changes framing.
