afaik there no such tag on an image in pdf so one has to wrap, i'll add

     \startPDFalternativetext{when will the german government provide 
full acrobat for free (livelong) to developers}
         \scale[s=3]{\rotate[rotation=30]{DE}}
     \stopPDFalternativetext

to play with but integrating something more nice also will b emore 
confusing ... the problem is that anything can be an image (liek a mp 
picture)
