Getting the data is not the problem. What I meant was that it might be
a bit harder to get a good UI layout in a character based
application. I guess what the parent wanted was something like the
      | THUMB  |     
      |        |     
  Centered file name   
    (X px x Y px)      
I am sure it could be solved in a number of ways. The file name could
be truncated if too long etc etc, but it would require a much smarter
redraw that tumme has now. One thing is sure, it will require much
more space. Of course it should be configurable too; personally, file
name and size is not interesting to me at all, in most cases.

I'll take your word for it. :)

So, when will we see your first addition to tumme? :) You have a lot
of ideas and seem to have technical expertice superior to mine.
