This might not be the best solution.  The purpose of the ‘alt’
attribute is to provide a textual alternative, which the file name
really isn’t.  It would be better to provide an empty value:

,----
| <img src="foo.png" alt=""/>
`----

I took a look at ‘org-html.el’ and changed the relevant line, but it
doesn’t seem to have any effect.  I think it’s being overriden by
‘org-export-html-format-image’, so I changed that as well.  Here’s the
resultant patch:
