Their PhotoBlog is interesting. The posts are sometimes basic: a photo with a caption, like these photos about BASE jumpers. Sometimes they pair an AP photo with a wire story, like this post on the Lions' victory against the Cowboys. Occasionally, the photographer will comment on his photos, like on this Sept. 9th post. Many of the photos are from AP or Getty, but MSNBC's own photographers have photos featured too.
MSNBC also promotes its photos via a Twitter account, which has a smallish following of 9,000. While this isn't is only a fraction of the follower count of flagship accounts like @msnbc or @todayshow, it's a pretty healthy amount, considering MSNBC isn't known for its photos. (Image twitter accounts for National Geographic, the New York Times and the LA Times are all over 100,000 followers.)
They also have a photo section on their site, which is a more visual version of their already photo-heavy home page:
From here visitors can look at some of their many slideshows, including this one on Afghanistan. That slideshow looks at Afghanistan in 172 pictures, each with a caption. It is much longer than the New York Times' "One in 8 Million" piece, especially when you count the separate slideshows for 2010 and 2009. That means it shares a lot more, but risks losing the viewer midway through. That may not be unintentional: the slideshow seems as though you could end at any point and get something out of it.
While MSNBC works hard to feature the photos themselves, its sections that feature only photography seem to be forgotten, leaving some of their efforts easily missed.
