Adjusting perl script which converts emails into pdf's

I am using a Perl script which converts emails and their attachments into one single pdf. When these are converted they are moved to another folder of my mailbox(from INBOX to DONE)  This script is made by a freelancer and works great, but after using the script for a while we would like some new features to be added. What we would like to have added: [login to view URL] in the body of an email are currently nog converted, this image should also be added to the pdf which is created by the script. [login to view URL] all the attachments which we receive are in pdf format, we would like to have image attachments to be added to the converted pdf. [login to view URL] a problem occurs during the execution of the script, the mail which caused the issue should be moved to an Error mailfolder, after that the script should continue to process the other emails. (error example: "Have error: Unable to open /nas/mntpt_clients/clients/S/Sepia/TodoSepia/[login to view URL] for writing at /usr/local/share/perl/5.22.1/PDF/API2/Basic/PDF/[login to view URL] line 395, <GEN0> line 107.", this was a mail with a protected, signed attachment.)  I can setup an email inbox and sent some example emails to this inbox for you to test with. I've attached the current script(without mailbox configuration) to this project. We believe this should be some rather small and easy changes for someone who is familiar with perl and generating pdf's.
