Hello Darkwing,

I know that Spreadsheet::WriteExcel provides a method insert_image($row,-$col,-$filename,-$x,-$y,-$scale_x,-$scale_y) for inserting pictures in the Excel sheet (sample bellow):

#!/usr/bin/perl
use strict;
use warnings;
use Spreadsheet::WriteExcel;

# Create a new Excel workbook
my $workbook = Spreadsheet::WriteExcel->new('perl.xls');

# Add a worksheet
my $worksheet = $workbook->add_worksheet();

# Insert image
$worksheet->insert_image('A1', 'perl.png');

I assume that you want specifically to insert an image in the background and not on the foreground.

If this is the case from a quick look up on the Internet I do not think that there is a module in Perl that can do that :(. But maybe I am wrong, maybe another Monk knows a workaround on this.

Never the less if you find a solution it would be nice to update the question so someone else in future can benefit on this.
