The following article
Heart of Manchester contains many pictures.
However if your browser is recognised as a handheld one or
an audio or braille reader, then a version without pictures should
be selected automatically.
Up-to-date Web browsers such as Firefox and Opera
(but sadly not Internet Explorer v6 or earlier)
offer you the choice of "Minimal graphics".
To select that, choose
View -> Page Style -> Minimal graphics
or something very similar to that - browsers vary.
In this case your browser has automatically selected the version of the article without pictures.
