On the web, half of the job is finding out your way through a website to the seeked data, so it’s always a good web design practice helping people to get orientated, even if  it’s not strictly necessary.

I find beautiful and useful Bkwld’s gallery pagination because it provides users with an extra bit of information, offering an overview of which site’s next offer is. As you can see, when you hover with your mouse over the navigation buttons a baloon fades in, displaying next/previous item’s name.
