Hi,
   i had problems with images.Now it's fine . But now i got the problem.I
have myDrawingArea :) but when i want to display images in sequence and
each after a second  i can't. It is true that i tried it wrong but how
to do it ? I tried the sleep() function but it it definitelly wrong :)
How does it work in gtkmm please.
