Something to try.
Go back to the original PDF Porfolio file and create a ZIP file from it.
Email out the zip file.
Use files.acrobat.com, or a "cloud" file storage/sharing service to park the PDF and the ZIP.
Get the link for the files.
Share the link via email.
With the zip on the destination computer, unzip it.
Or, with the PDF downloaded from the cloud, open and work it.
Be well...
