It turns out that the theme for this blog does not display caption information for featured images. This is necessary in order to ensure that appropriate credit is given. There is a plug-in we can add that will automatically display the caption metadata for featured images. Can we explore adding this to the blog (pending security review)?

For now, we can capture the image credits in an "About this post" section at the end of each blog post.
