Shortcode: Recipe: Give user control of printed images

In my test, because of the images, the print ended up being 10 pages long instead of 2. I think users would appreciate an option to print without images, or maybe images scaled to 33% of size, or printing just the featured/first image.

No files, tests, or entry points are named. Start by locating the shortcode's print and image-rendering code, then clarify which image-control behavior is wanted: no images, scaled images, or only the featured/first image; done should include the selected behavior and coverage for printed output.
