I have a couple of PDF files that when I open them in Goodreader or Readdledocs, will not display correctly. They are sales flyers with formated text, colored backgrounds and pictures of products. Everything looks okay except most of the product images do not display. On other PDFs made by the same people (my company's marketing dept), everything is fine. File size is not an issue as this happens on smaller and larger files. I have no file bigger than 5 MB or so. Any ideas?
