That's the wrong approach.  You should upload your PDFs into Upload a
file CFs and extend the column map (using callbacks) to allow you to
interpolate the file's URL within RT inside your format string.

RT isn't thumbnailing what you upload when it displays the CF value for
you.  Since it is an image CF, RT simply spits out an HTML <img> tag
that points to the image URL within RT.  I don't know of any browser
that renders PDFs in <img> tags.
