View Thumbnails on Access Form (like pdf,doc,jpg,psd, etc)

[MoxieCraz]

I am creating a database of marketing assets and have a textbox named[filepath] that has the file path to a file (pdf, doc, psd, etc). I have an image [Preview Window] that has the control source set to [filepath]. I am able to view jpg and bmp files, but can not view pdf, doc, psd thumbnails. How do I make this work?

Thank you in advance for you help.
