Alt text goes on LAST, after the images are final. If a listing is ever re-pushed from the supplier the images get replaced and the alt text goes with them. That is exactly how the Cross listing ended up serving Etsy's own AI-written alt text.
Personalized Cross (4514186525) is already done, 9 of 9. Skip it.
Leo is already done too. It is not in this list. Do not touch it.
In the Etsy Seller app: Listings → pick the listing → Listing tab → pencil icon on Photo and video → Alt text icon → pick the photo → paste → Save.
The photo order is not the same on every listing. Five of them differ. Match the caption to the photo you are actually looking at. Do not go by slot number alone.
