This is the Focus theme from Charlie Lockhart at Blueballdesign.

Here are the guidelines to follow for your BannerZest banner size based on selections you make in the theme’s Style menu.
Height: make the banner the same height as you select for Header Height.
Width:
800px theme width: 696px wide banner
1000px theme width: 896px wide banner
1200px theme width: 1096px wide banner

Publish the Bannerzest theme to its place on your server and select "Show HTML" (see Publish at right)




Copy Bannerzest's code to the clipboard

When you click this button, you'll be presented with another window (see Copy at right)






Use Textwrangler to open index.html
TextWrangler

Now we have the necessary code copied to our clipboard. The final step is to open the theme's index.html file with the text editor you've selected and paste the code in the correct location. To open this file, right click the theme in Rapidweaver's theme drawer, choose "Reveal Theme Contents In Finder...". This will present you with a folder called "Contents". Open it and you will find the index.html file. Right click on this file and navigate to your chosen text editor application. In this example I chose TextWrangler. (see Textwrangler at right)



paste your BannerZest code here
Paste here


Scroll through the code until you find a place that matches that shown in the photo (see Paste here at right) The code you copied from Bannerzest is still on your clipboard. You want to paste it in the right spot. Delete the line of code that Charlie placed here to help you with the BannerZest modification. Just paste in the code from Bannerzest in its place by either choosing edit>Paste from TextWrangler's menu or simply by pressing the Apple-v key combination (command-v). Now that your code is inserted, save the file and view the results.

Remember, when you use this technique and publish your site, send me a link so I can put your site in the showcase!

They don't get any easier than this!!
