Re: image size limit?

[Richard M. Stallman]

    Yeah, me too -- in many cases I just wanna check do a quick check, and
    seeing just the upper-left corner is good enough, so I do this with
    pictures up to about  3840 x 3072 pixels (that's triple my display
    size in each dimension).

That is surely an unusual usage.  I think it is ok if this requires
you to set the value of max-image-size.
