Hi leocharre, Thanks for your quick reply.

Like this:

#!/usr/bin/perl 
use strict;
use warnings;  
use File::Find;

sub callback {

    my $file = $_;
    rename $file,"reference_$file" if -f $file

}

my $dir = 'C:/Image_Repository';

find (\&callback, $dir);

Of course, there is always More Than One Way To Do It, so you can "hand craft" it if you enjoy lots of typing, but it probably won't be as efficient as using File::Find.
