I found a bug in the file reader that causes it to always rewind after the
first picture when there are several pictures in the same file. But since
the bug is in scriptable code, then you can fix it yourself easily by
putting this code in ~/.gridflow_startup :



require "gridflow/format/main"
GridFlow::GF_VERSION=="0.6.3" and
module GridFlow
  class Format 
    def rewind_if_needed
      thispos = (@stream.seek 0,IO::SEEK_CUR; @stream.tell)
      lastpos = (@stream.seek 0,IO::SEEK_END; @stream.tell)
      thispos = 0 if thispos == lastpos
      @stream.seek thispos,IO::SEEK_SET
    rescue Errno::ESPIPE # just ignore if seek is not possible
    end
  end  
end
