If the logo is in a header, then you would open the header pane and change
it there and it will change in all pages to which that header applies. I
say "all pages to which that header applies" because:
a. The document may be divided into Sections, each of which has a
different header in which case it will be necessary to change the logo in
each of those headers
b. Each Section of the document can have several headers - a first page
header, an odd page header and an even page header, each of which could be
different.
If the documents are all very similar, it may be possible to automate this
process with a macro. For a client who sells a suite of documentation to
other companies, I developed a utility that allows them to browse to the
folder on their system where they have stored the file containing their logo
and when they select that file and click on a button, a process runs that
inserts their logo into the headers of several hundred documents.
Fortunately in this case, there was not much variation between the
documents, so there were only a couple of different "cases" to be catered
for, and as it was a system that was being sold to many different companies
and would be used by each of those companies, it was going to be used many
times and was therefore worth developing the modification that was necessary
for each of the "non-standard" cases.
