Document `@@images-test` view

[stevepiercy]

in theory this should work, but its broken, hmm, smells like a bug https://classic.demo.plone.org/en/demo/an-image.jpg/@@images-test

According to plone/plone.namedfile#174, the issue has been resolved, but has not yet been deployed to the demo site to test and document.

https://classic.demo.plone.org/en/demo/an-image.jpg/@@images-test is working now, after the update to Plone 6.1.1 final of today.

@stevepiercy should I document this under 'Styles test rendering' in classic-ui/theming/create-add-on.md again?

[stevepiercy]

@Manas-Kenge I think it belongs under https://6.docs.plone.org/classic-ui/images.html, but I'm not sure where in that page. It might be either a new section "@@images-test view" or get spread across several subsections under existing sections to provide context (examples, cover, contain, picture tags, stored scales, clear). Let's get an opinion from @plone/classicui-team and @jensens, as they likely have experience for most common usage to guide the direction.

The intent of the view is to visualize for editors how an specific image is possibly rendered and to give developers writing templates an idea whats possible. So, where do we place this information?

[Manas-Kenge]

@jensens where should I put the documentation?

[jensens]

@stevepiercy probably best answered by you?

[stevepiercy]

@jensens I don't know. That's why I asked in #1921 (comment) for you and the members of the @plone/classicui-team who actually might use this feature to provide direction.
