As opposed to one? Of course. It's only common sense. Ideally, given that eBay allow up to 12 images at no charge, you should use as many as are necessary to give prospective buyers the best possible idea of what the item looks like, its flaws (if any) and its good points. As your photos provide a substantial part of your item's description, why wouldn't you take as many as possible to show it in its best light?
