No, displaying more than one representation at the same time (the ALT,
and the image) can be very helpful to some users (it's something I find
extremely useful for images I don't understand, and for this reason on
mouseover my browser, displays TITLE and ALT, and is one of the reasons
why Mozilla is basically inaccessible to me.)  So whilst yes in general
what you say is a good suggestion for default rendering - there's nothing
wrong with showing ALT when there is not a TITLE attribute. Should in
your description is excessive, I don't like disobeying _should_s but
would be forced to.
