Yet another small problem: I my photo captions, the photographer should be right aligned and in one line, i.e. if it doesn’t fit into the last line of the caption, it should move to the next line. ATM I’m clueless...

That’s not enough (also not a MWE):

\define[1]\Foto{\hfill\hbox{\tfx Foto: #1}}

Doesn't \wordright do what you want?

I always forget about that. Thanks for the reminder! Best, Hraban
