Okay that works, thanks. The full syntax is


in the preamble, and the line


in the file.

There's still a bug though, pdflatex/graphicx (not sure which)  
shouldn't be parsing the file as having extension .80.pdf, I don't  
think, but as having extension .pdf. (The above workaround just tells  
graphicx to pretend that a file with 'extension' .80.pdf the same as  
a file with extension .pdf.) Maybe others disagree that this is a  
bug, though.
