I have a Kobo Forma. Almost all my ebooks come with an image for the cover, and when they don't, I get Calibre to find and download a cover.
Some of my ebooks come with images. For example, maps and photographs. Almost always, these images are full colors, unless the photos are from, um, the 1970s or earlier when film was still black and white or grayscale.
Because my Forma only does grayscale, I would like all images that are in my Kobo Forma to be grayscale. This is to save on limited space (and perhaps a secondary benefit is faster page turns / image-loading).
How can I make this happen?
