The pictures kind — what a template owes an ; two shapes, one promise.
The pictures kind: a field that points into the media library and promises
its target is a picture — which is what lets a template render an
<img> without checking first. One kind, two shapes:
| Shape | Stores | Admin field type |
|---|---|---|
| Single | one reference (media) |
Image |
| Multiple | an ordered list (collection) |
Images |
The shape lives in the data type, not a setting — a template always knows whether it holds a picture or a list. (The systems that make one-or-many a formatting switch teach every template to guess.)
Alt text, title and dimensions live on the library asset, not the field — described once, correct everywhere the image appears.
