Display Blobs on Reports??

I need to create this typical report in which I need to show that actual content stored as blobs in the SQL Server Database. The problem is that some of them are PDF documents while others can be word or image files.

So my complex problem if broken into two are :

1. What is the best approach for creating reports which have content in case of a Winform application ( ReportViewer or Crystal or )

2. Since the content is of varying nature , is there some solution to first have them change into a common format and then have it displayed ( for ex: convert .doc and .gif files to PDF and then show it ) or is there some container within a reporting tool which has suitable plugins to recognize the content types and launch the appropriate program for displayng it.

Any leads , clues or meaningful thoughts will be greatly apprecitated.
