Rather than optimizing only for the latest trend, it'd tremendously help to provide content people are looking for. Google usually is quick in weeding out fluff, of course it also helps to have a sane URL-structure without keyword-overload and maybe naming images appropiately - not only for the added benefit of SEO (Image Search comes to mind) but at the same time you provide some context for people with screen readers... Following basic accessibility concepts, providing some context to pure image content go a long way and should be done for the sake of the visitors to the site and not SEO. edit: Now that i've read the article from Google Cache i realize all my points have been raised there too - so, 100% agree..
