I was able to see the issue as well when I checked this on your jotform http://www.jotform.us/form/53483882856168
In the PDF report, the link and images of uploaded files have incorrect url/link the reason they are not showing and not available to download
BUT they work just fine in the Submissions page view of the form in your Form Builder.
Our higher team support are aware of this glitch already and are working to resolve it asap.
We will notify you here once we have update on the fix.
