If I save a PDF claimfrom my mailbox, then disappear my uploaded images. I have created a claim form where individual invoices can be uploaded, e.g. receipts. I save the PDF with these uploads and send it as an attachment in the mail to my director. He signs for approval and sends the pfd back again. When I click on PDF example in the mail, I do see the uploaded images. But when I save the signed PFD, the images have disappeared.... How is this possible? see printscreens.
Make sure you do not open the file at any moment in your browser or using a non-Adobe application like Apple Preview or Microsoft Reader. These applications are sub-par and can corrupt a file just by opening it. Save the file you get directly and then open it in Acrobat.
