Thank you for your post.
Currently, FileMaker Pro on Windows OS cannot insert PDF files as an image. They can only be inserted as a file. However, on Mac OS X, you can insert a PDF file as an image. If you then move that database file to a Windows machine, the PDF file will display as an image.

These suggestions are read by our Development and Product Management departments where they are then discussed and considered for a future release. Although I could copy your post and paste it into the web form, there are some additional questions asked that only you can answer.
As a work around, it's possible to configure a web viewer to display a PDF as an image. This should work for both Mac and PC.
