I used to maintain a website for a church and here is a solution that I used. I created an external file named, mybanner_small.js
var cText = '';
cText += ' <p id=\"heading\">';
cText += ' <img alt=\"Kingdom First Ministries International Image\" src=\"images/banner_small.png\" />';
cText += ' </p>';
In this case if the banner filename changes I just had to update the .js file with the new name and the rest of pages would display the change accordingly.
Be sure to ...
1) escape characters as needed in the .js file so the html is composed properly
2) place the script tags in the html file in the location where you want to see text unless of course if your using css for page layout.
