I just put one up on my new blog HongKong360 and the guide posted here was very easy to follow. Thanks!
However, I wish it would scale better. I had to make it half its default size to make it fit into the layout but now the thumbnails are jaggy and some of the labels can not be read because only half of the text can be seen.
Any chance of making it scale better. I think 400 x 300 is too big for it to be used as a banner object.
