As with everything on eBay, it doesn't matter a dingleberrry mcnugget squat what is "ethically" right or what is wrong. And while I think wilsonsingles' listing is clear as a bell, the fact is that if you put multiple items in your pictures, you leave yourself open to buyers who will try to take advantage of you. Period. That is reason enough, for me, to never put multiple items in a picture.
I agree that multiple items in a picture can help promote your other items, but for me that upside is not enough. I find there are plenty of other ways to promote your other auctions/items. (a bold/red "check out my other auctions" in every item description, for example)
