[SL] Invoice.tex - path / relative path to images?? Using a <%variable%>??

[Stroller <lin...@my...>]

Hi there,

After a recent hard-drive failure on my server I'm currently redoing  
the layout of my invoice.tex
I had been foresighted enough to do a daily pg_dumpall & email the  
results to myself (saving a copy on my desktop PC) but had not  
thought to backup this important file!! :(

Anyway, if I make the following minimum case invoice template & email  
an invoice to myself, only the first image (A:) is shown:

   \documentclass{minimal}
   \usepackage[a4paper,landscape,dvips]{geometry}
   \geometry{a4paper,landscape,
             nohead,nofoot,
             left=15mm,right=15mm,top=1cm,bottom=1cm}
   \usepackage{graphicx}
   \usepackage{ifpdf}
   \begin{document}
   \thispagestyle{empty}
   \noindent

   A:
   \includegraphics[scale=1]{/usr/local/sql-ledger/templates/stroller/ 
logo-colour}

   B:
   \includegraphics[scale=1]{./logo-colour}

   C:
   \includegraphics[scale=1]{logo-colour}

   \end{document}

In the default letterhead.tex the path to the image files is defined  
as "../<%templates%>/<%language_code%>/logo". Is there some similar  
variable which allows me to say "../stroller/logo"? EG: ../<%user%>/ 
logo"? I have tried <%user%>, <%employee%> and <%employee_id%>, none  
of which work, but I thought there might be another variable I'm not  
aware of?

Strangely, if I compile the invoice.tex manually (I tend just to use  
`rubber --pdf /usr/local/sql-ledger/templates/stroller/invoice.tex`)  
then LaTeX only b0rks out on the _second_ image (B:). Even though I'm  
working from my home directory, "\includegraphics[scale=1]{logo- 
colour}" seems to look in the same directory as that in which  
the .tex file resides - "./logo-colour" appears to look in the  
current working directory (which is what I would have expected from  
C:, too, to be honest).

Any suggestions?
