I have been recommended to join an email list called The Weekly Haftorah. The email is sent once weekly and it explains the weekly haftorah. It gives some historical background into who the author of the haftorah was and what the context of the haftorah was. It then explains the haftorah and explains the connection between the haftorah and the weekly parsha. It also then gives over some lesson learned from the haftorah.
The email also has images of artistic renderings related to the haftorah's story.

You can subscribe to receive the email by emailing Reuven Ebrahimoff at haftorahman@haftorahman.com

You can also read the sheet online at: The Haftorahman , though it does not include the images.

Since I started getting these weekly emails, I have actually listened to and enjoyed the haftorah in shul, rather than either falling asleep or looking for other things to read, as I used to do.

Check it out.
