New keyboard accessibility plugin demo - Image Viewer design

Hi everyone,

After starting work on the demo markup and thinking of actual
implementation, we have discovered that the implementation of a horizontal
scroller for the image thumbnail requires either:

1. A fixed / absolute layout, or
2. A Javascript scroller to handle the interaction.

There are disadvantages to both these approaches. Option 1 will have reduced
accessibility and reduced personal customization if the demo is in a fixed
layout. Option 2, though a common approach, adds more Javascript to the demo
and requires integration between the keyboard plugin and the Javascript
scroller.

I don't think either of these options are desirable at the moment given that
we want this demo to be a clear, inclusive example of the keyboard plugin.

What I propose is that the design of this demo be changed slightly to use a
grid of image thumbnails instead of a horizontal scroller. This still
accomplishes what we want for the demo while maintaining good accessibility.

We will use a small number of thumbnails to reduce the amount of vertical
scrolling, and the revisit the Javascript horizontal scroller / keyboard
plugin integration as a future iteration.

Does this sound like a reasonable approach? Thoughts and comments
appreciated!

- Jonathan.
