When you hover your mouse over the photos you will see 2 icons to click on. The first lets you see a larger version of the photo. The second will redirect you to the blog article that contains the photo. In some cases the article will contain further photos.
A quick way to see all posts that contain just photos is to click on the “Photos” tag in the tag cloud.
