It does the job in a non-intrusive way and looks great

I was looking for a plugin which would allow me to have different headers on some of the pages of my site, but to be done in a simple way which did not get in the way of anything else.

The Unique Headers plugin does just that. It is as simple as adding a featured image and is in the same area of the admin page, so you can get on with whatever you are doing and ignore it when it isn’t required, but easily use it when it is.

There are other plugins which do a similar job and give you a variety of options, but why would you need them?
