With all the kerfuffle about Flickr and its ToS, I've been thinking Pinterest is a better place for advertising SL products. They even have a (free) Business account mode.
and it works well in conjunction with a blog, too. Problem is that flickr is so well populated with SL people, and it's frustrating to suddenly lose that community.
Either way, I'm taking down all blog links, ads and links in credits on my flickr (I figure text-only credits must be fine) and will use it only for arty/WIP pictures.
