Here is another version. This version resizes the images to fit the
static control.
Place static control on your dialog box, give it an ID, attach a variable
to it, change the variable type from CStatic to CSlideShowCtrl

Here is a very simple one I wrote in 10 minutes.
It doesn't do scaling, you want to scale the images so that they are all
the same size you will have to Draw the Image yourself.
