Each of these is the name of the class to make a link with a background image for that mime-type
<a class="application-pdf" href="somthing.pdf">application-pdf</a>
If a mime type is missing that you need, to add it to the collection we need a couple of things:
- The mime type name
- small image to use
All of the mime type images we have so far have come from:
- Tango Icons, under Creative Commons Attribution Share-Alike license
- Silk Icons, under Creative Commons Attribution 2.5 License
So please check these sites first.
If you can't find a image, feel free to look around elsewhere. But we need the image to be free of copyright issues.
