Spreadsheet_Excel_Writer picture in header

Hi! Is it possible to get a picture in a Excel-file with Spreadsheet_Excel_Writer? In Excel XP you can do that but I also did not find whether it is possible in the Perl Module now (where the pear module is ported from) Actually I also need a way to get different Headers for page 1 and the rest. This - however I do not even find how to do in Excel itself. But maybe it is still possible to achieve with the Perl/Pear module? (there are also no formats in Excel itself) Any help on that would be highly appreciated Daniel
