Do Photos Increase Subscribers?

BloggerDesign iPhotoIf I look back over all the blogs I read, most have photos associated with their posts. Maybe not every day, but quite often. It makes me wonder, do photos increase the number of subscribers to a blog?

If you stop and think about it, there are two kinds of people out there, the analytical/text people and the visual people. There are those than buy the New York Time’s best seller books and those that would prefer a magazine with less reading and more pictures. So, with that in mind, if your blog posts don’t include images, are you just targeting one audience then?
