I am trying to put images into a horizontalList. I can see
the image(s) on the screen but it seems that they overlapping one
on the other one - not in a row. Naturally, what I would like will
be to have each images showing one-beside-the-other-one.
By default, a HorizontalList can only display text - a Label,
a labelFunction. To display an image, the image has to be in a
component (the itemRenderer). You can't just add the image directly
to the list, as you are trying to do.
