@RbnJrg...I've had a look at your image in the various formats and I would completely agree with you that KF8 devices can use the "background" property without any problems. But when I checked your mobi "background" image on E-Ink emulation on the older Kindle Previewer your background image was missing. I also realize that many indie authors who format their own ebooks don't really care about ensuring that KF7 image formatting is done correctly -- because it's such a hassle to dual format all ebook images for correct displays on both KF7 and KF8 devices. Most assume that no-one uses E-Ink devices any more. Unfortunately there are alot of E-Inks(older KF7 devices) still being used out there. So if someone who owns an E-Ink buys your ebook and cannot see your reference images because you've used the "background" property then there is a good likelihood that he/she will complain about this in the reviews of your ebook on Amazon, perhaps leading to poor sales of your ebook as a consequence.

As far as I'm concerned, this isn't really a big deal. Indie authors can and should format their Kindle ebooks how they like. But it is perhaps worthwhile just to highlight one major downside of using the 'background" property to display images on older KF7 devices.
