IKImageBrowserVIew has a much better way to handle this specific
labelling requirement.
The objects it stores should implement the informal protocol for -
imageTitle and -imageSubtitle, and the view will draw those strings
below the icons for you.
Here are the methods I have in a simple custom object I use - I think
I originally got this from one of Apple's samples though I'm afraid I
forgot exactly which one. It simply provides the browser with the path
to each image.
