Not going to happen.

My goal was to make the images take up very little screen-real-estate, not to make the buttons readable. People with small screens or who run their browsers in a small window might want to look at it.

Besides, now that I've created the tables and sliced the graphics, it would be a royal pain in the arse to do it over again. You can still see the button names when you hover over them.

If I ever change the layout of the page, it's going to be to add front-panel pictures.
