I think you're putting too much emphasis on the words "for an image" in 
what I wrote.  I think my intention was to avoid cases where it's 
pointing to itself.  In practical terms, it just needs to point to file 
in a format that browsers support for <img>, but HTML has never 
explicitly defined which image formats browsers should or should not 
support, and I don't think it should.
