Set up a header to include an external file such as a product logo
Let’s start simple. From your template specification, you know that the headers on the toc-first, body-first, and index-first pages should include just the product logo. This is an external file.
You also need the product logo in the headers on the first TOC and first index pages. By default, a PDF plugin doesn’t include header and footer definitions for toc-first or index-first page masters. Later, we’ll look at how to create new header and footer definitions, but for now, let’s just look at how to add an external file to an existing header definition, body-first-header.
