I’m curious: Did people/apps ever attempt to bundle alt text with the image as metadata? (Like EXIF?)
That feels like the right place to put it, so then it could be read by apps/browsers, and also travel with the image on save etc. Rather than specifying it as out-of-band text like we do today.
@mwichary The answer I've seen before on this is that alt text is very much context-dependent.
For example, an alt text describing the relationships of the people in a 19th-century photo will probably miss everything about important about the historical clothing styles, or about the photographic process and how it affects the resultant image.
