Is skipping the photo really better than mentioning the filename in  
this case? It's not purely decorative, it matters that it is there. A  
text-only but visual UA like Lynx should should the filename with a  
download link for instance. In any case, since you described a  
behavior difference between omitting alt and specifying alt="", I  
presume that there's cases where either behavior is useful.

Furthermore, as Chaals mentioned, adding a default empty alt text is  
contrary to WCAG.

My comments are not speaking for the group, only for myself. Also,  
I'm not suggesting to remove anything. I think the alt attribute  
should be retained. But I think that it should no longer be required,  
since requiring it always leads to worse accessibility and media- 
independence in some cases, in my opinion.
