Can I load a JPG/PNG Table Image as a Drill? Why would I?

Drill (.drl) files, with all the flexibility, tools, and layout functionality available, are the preferred method of using the system. Table images should generally be thought of as static "cloth", with all other elements sitting on top, and hence a JPG/PNG is often loaded "as a Table Image". However, if you have a set of JPEGs that comprise a lesson, loading the JPEG through Drill-Load provides the benefit of mouse wheel or arrow key next/previous drill and r for a random selection.
