The Transmission WordPress Theme is a stunning and professional free theme with the flickrRSS plugin integration. This theme uses custom fields you can use to add an optional image to your latest blog post. Simply upload the image you want to your topstory-images directory and add a custom field with topstory_image as the key, and the name of the image as the value.

The Transmission theme has a fully widgetized sidebar as well. This includes the search box, as well as the Feeds section, so you have complete control over the sidebar. And best of all, this free download comes with 8 different styles to choose from. Don’t have a favorite color? Just use the AIO (all-in-one) version to have a dynamic style switcher on your site where visitors can choose their preferred style.
