Re: [dooglus@gmail.com: display problem after renaming open image files]

[Richard Stallman <rms@gnu.org>]

    Another possibility would be to allow one or several of
    a) a buffer
    b) an overlay (use the covered text)
    c) a cons of two markers
    d) t (use the data covered by the overlay itself)
    as an argument to the :data parameter of an image property.  Then we
    would not need to copy material back and forth.  One would need to
    think about what could happen when the material references by :data
    changes.

I think that is a fine solution, and should be easy to implement.

There's no immediate need for all of these options -- any one would
allow use of the buffer contents, and that would be enough.  Of the
four options, b is both clean and general, and simple.  Would someone
like to implement that?
