How to view the jpg & tif files as OLE object

[Fred Ho]

I have added the OLE blunded object to view the pdf file with the code :
OLE1.class="Ado be Acrobat 7.0"
....
Besides, I can view the bmp file using the code
OLE1.class="PAI NT"

But what should I use or how the code change for jpg and tif files?
Thanks a lot!
