This also happens with other types of variable. I ended up creating a 
function to test, and calling with a conditional markup:
$Conditions['bi_isnull'] = 'bi_IsNull($condparm)==""';
function bi_IsNull($e){
   return (!empty($e) && substr($e,0,3)!='{*$' && substr($e,0,2)!='{$' 
&& substr($e,0,3)!='{=$' ?$e :'');

Called with:
  (:if bi_IsNull {$$File}:)Photo(:else:){(ucfirst "{$$File}")}(:ifend:)
