I have purchased many products after something catching my eye in the scrolling gallery.  The item I looked at might not have impressed me that much, but then I've been more impressed with items in the scrolling gallery.  So each to their own I guess.

I have may buyers regularly by many multiple purchases from me, I just assumed it was because of the scrolling gallery.  I didn't realise that it made people giddy and they don't like it.
