Something I've been experimenting with is a back-link to an anchor just
past the image, thus preventing your users from having to read the whole
first part of the page again.

E.g. "Use your browser's back button or [link back and continue reading
page] ..." ([] indicate a javascript.go.back link).

Is there a way to safely and accessibly implement a JavaScript back

The browser provides a 'back' function and should not be generating
content into the document redundant to this.

It is OK to put a scripted backlink in the page, but there should be
voice over in the page text that says something like "use your browser's
back button or this link to..."

Yes, we need a palette of browser techniques and a palette of author
techniques that are compatible in mix-and-match fashion.  The
suitability of the techniques on one end of the comm link should not be
entirely dependent on which of the other end techniques are implemented
for this particular browse session / page fetch.
