So true Paddy, mouse over the V4U Player in the lower left corner and click to go and download the V4U Player

The key commands for the V4U Player are also included (in the right area)

to help noobies who just started using the V4U player.
If people are sharing V4U Slideshows at their website, including this feature will help their visitors to download and learn the V4U Player instantly. At the same time visitors can be inspired by a world of creative minds who have submitted their V4U slideshows at VIG
I hope this explains it.
