Years ago I ran a photo collection that was based on a WordPress blog, I rolled out around 30+ images a day (each as a separate blog entry) on a sustained basis for more than two years and was pretty aggressive about creating incoming links.
In the first few weeks I noticed that Bing had flagged me as a spam site and they seemed to do a manual review, then did a complete reindex, and were sending me a lot more traffic pretty quickly after that.
