I have always told my clients that every blog post needs to have at least one image, and I stick to that rule myself. I even go so far as to set up a separate field for the "primary post image" in my Drupal website installations so that an image must be uploaded. (That also has the benefit of giving the website a specific image associated with that blog post for slideshows and other displays.) I usually mention that images help generate interest in your content, but don't go into a lot of detail unless asked regarding all the reasons for including an image. So, here are ten benefits that I see to making sure that every time you write a blog post, you include at least one great image.
