This has the disadvantage that the the image becomes presented as a link - e.g.
in screenreaders - rather than as an image.

>  <img src="thumbnail.jpeg" data-fullsize="big.jpeg" alt="textual replacement">

This could probably work.

>  <figure>
>   <figcaption><a href="big.jpeg" rel="...">caption</a></figcaption>
>   <img src="thumbnail.jpeg" alt="textual replacement">
>  </figure>

I think this has the same 'becomes presented as a link' problem.

>  <object data="thumbnail.jpeg"><object data="big.jpeg">textual
> replacement</object></object>

This seems elegant - though the UA support might not be tip-top.

>  <details>
>   <summary><img src="thumbnail.jpeg" alt="brief textual replacement"></summary>
>   <img src="big.jpeg alt="detailed textual replacement">
>  </details>

This example assumes that the non-sighted needs a longer description of the big
image copy than of the thumbnail copy - I don't think that makes sense. At the
same time, it probably does not make sense to leave the @alt of the big.jpeg
empty - as that would mean that there is a summary description for a
presentational image, or what? May be it could make sense to simply ommit the
@alt of the big.jpeg ?

When you say 'pave a cowpath' then I assume you mean an *existing* cowpath. The
spec could still point out one or several useful ways to do it - as the usecase
seems common enough!

I suggest that you add examples for how to do this - one or more scripted
solutions and one or more no-script solutions. The non-scripted solution could
use <figure> and-or  <details>.
