If you like to add a header image to the Black-Letterhead theme, follow this thread in the WordPress Support Forum. You can also check out http://fireofthemind.com website to see how a header image was incorporated in the Black-Letterhead theme.
I also would like to add the step-by-step instructions made by envelooponline.
One of the shortcomings of the Black-Letterhead theme when it first came out was, there was no spacing between the images and the text. I’ve added margins of 7px around the images located in the post section. Notice, there is now spacing between this Fantastic Four image and this text.
The change is cosmetic, but it makes a big difference to the layout and presentation. To add space around the images, edit the “style.css” file located in the Black-Letterhead directory and use the code below.
I also like how Aitortxu has done here.
Welcome to the Black-Letterhead page, a WordPress 2.1 theme based on Robin Hasting’s theme called Letterhead which in turn is based on Kubrick, the default theme for WordPress 1.5.
I modified the colors of Letterhead and called it Black-Letterhead because of its black background. The color scheme was inspired by the team colors of the San Francisco Giants, a Major League Baseball team.
I entered this theme in the Wordpress 1.5 Theme Competition hosted by Alex King. Since then, numerous websites have popped up all over the world using the Black-Letterhead theme. Some have altered it even more by using different color schemes.
I created this page to provide support for current and future users of the Black-Letterhead WordPress Theme. You can download the latest changes from the download page.
