“In the last few tutorials we have been looking at various parts
of what make up a graphical user interface. We’ve created labels
and buttons and have attached images to a label (and a button if
you did the homework). We have also associated an action with
pressing a button. In this tutorial we’re going to put these
together to make a simple image viewer application. As with the
previous tutorials, this will only work with images which are saved
as a “gif” format. Also, a word of warning – you need to do
pretty much all of the code before any of it will work.”
