The reason have having a blank alt attribute is because alt is mandatory, so
the HTML would be invalid if it were not there.  It's mandatory for the
rather naive reason of forcing authors to think about the
content (in reality, they or their tools will simply stick in a blank
value, with exactly the same meaning - I didn't think about this - as
omitting it in older HTML where you could do so legally).
