Big Box request: display specific type of image (e.g., Cpanel, Cab) upon request

So we're able to download all of these really cool images from emumovies (controls, cabinets, PC boards), and it would be really helpful to be able to assign a button to display a particular type. For example, on my control panel, I have a dedicated button labeled "Control" that I'd love to be able to configure to display the associated graphic from say MAME/Cpanel.
