Gina,

Depending on what kind of server, you might have Extended SSI, with the if
statement, etc.  For example, Apache.... (Others?)

Given that, you could do a regex compare of the DOCUMENT_URI (the
*requested* page) in one of your header files.  Given that you can
successfully compare the URI to one of the many IF statements in your
headerfile, you can then bring in the appropriate file.

Example:

page a/b-dir/cfile contains a call to header z/y/x

In header file z/y/x, you have a series of statements like

normal header stuff
<!-- Different pictures for different files -->
<!-- #if expr="\"DOCUMENT_URI\" = /a-dir/" -->
<img src=a-dir.jgp>
<!-- #elif expr="\"DOCUMENT_URI\" = /b-dir/" -->
<img src=b-dir.jgp>
...
<!-- #endif -->
Rest of the normal header stuff...


Of course, I haven't hacked it into working, but from the example I cut
from the Apache doc on SSI, and the definition of DOCUMENT_URI, it
*should* work.

Of course, you'll have to let me know if it does... :-)
