Today I found the banner graphic!
Now all I have to do is find the php script which includes the link to the other script which requires() the script that links to the page that includes the script that calls the function that builds the script that places the banner.jpg onto the pages!
And then! > hey...I can change the damn jpg.
Here's a hot idea: a pdf with a picture of the index page on it. and arrows pointing to the page elements and on the other end of the arrow a name like "theNameOfTheDocumentThatContainsThisPageElement"
Then users of the blogging system can edit their pages without the seek-and-destroy method of editing somebody else's php work.
