I don't know what command perlapp would need to include external files, but as an alternative, Tk uses the base64encoded format for storing images internally, so it's easy to just Base64encode your images, and include them as data right in your script.

If you have many images, you could put them all into a helper module.

I did just look at the Perlapp doc, and it says you can use --bind file to include external files. Read the doc link for details.

#!/usr/bin/perl -w
use strict;
use Tk;
use Tk::PNG;  #must load appropriate Tk module for image type
use MIME::Base64;

#this method works as easy as it does, because
#Tk needs it's images to be base64 encoded anyways,

#use this to encode
#my $file = shift;
#open (FH,"< $file") or die $!;
#my $photo = do {local $/; <FH>};
#my $content = encode_base64($photo) or die $!; 
#print $content;

#don't forget to '' quote
