The PDF Embedder AddOn integrates with the PDF Embedder plugin allowing you to email PDFs and have them display inline rather than requiring the user to click on the PDF icon and download it and have it launch in Acrobat Reader.
The AddOn is compatible with the Free, Premium and Secure editions of PDF Embedder.
You can control whether the PDF is at the top or bottom of the post by using the Image/Attachment Location setting on the Image tab.
