Question : SharePoint Document Library

I'm using SharePoint Foundations 2010. I have several document libraries set up & they are all working perfect. My question is, when ever a user uploaded any form that is a Microsoft Office form such as Excel or Word, in the document library it has the pretty little Excel or Word icon next to the name of the file. If anyone uploads a .pdf it uploads fine & opens fine but it has a blank icon next to the file name. Is there any way to make the .pdf icon appear next to .pdf files?
