Add a PDF Thumbnail Hover Preview Column to a Document Library

I got this request from Jewell from my previous post:

Display PDF Thumbnail Preview on Hover in Search Results Web Part

“Is there away to apply this to a document library?”

Here are the steps to add a pic of a magnifying glass to a column in a Document Library.

So that when your mouse hovers, it displays the first page of the PDF inside an iFrame window.

The only down-side to having this implemented, is that as the user hovers over each PDF, it needs to download the entire PDF file to display the first page.

* Document Library with the PDF Preview column added

pdfs - All Documents

* On Mouse-Over

pdfs preview

Step 1: First you’ll need to create a workflow that copies the Document Name to the Title column.

Follow this post to do exactly that:

Step 2: Go to and download the Scripts Zip file.

You’ll need the 3rd Example files uploaded to a Document Library to hold your script files.

Step 3: Open up main.js and replace the text with this modified version: PDF thumbnail script .docx or the pastebin version:

Step 4:  Create a html file in the same folder as your scripts and paste the following:

Don’t forget to change the paths to your script files.

<script src="/server/site/scripts/jquery.js" type="text/javascript" ></script>
 <script src="/server/site/scripts/main.js" type="text/javascript"></script>
 border:1px solid #ccc;
Step 5:
Add the HTML file to the source of a Content Editor Web Part in the document library that holds the PDF files.
Step 6: Add a Calculated Column in the Document Library, call it Preview and select type returned as:
Number (1,2,3…).
Add the following from here:
or from here:
="<DIV><a href='..\"&Title&".pdf' class='screenshot' rel='..\"&Title&".pdf' ><img border='0' src='/_layouts/images/MAGNIFY.GIF' alt='' style='padding-right: 5px; padding-left: 5px; vertical-align:bottom'></a></DIV>"
That’s it! Now hover over the magnifying glass image and you should see the PDF thumbnail display.
Any questions or comments, post it below. Thanks for reading.
