You can use generic icons for non-image filetypes, or use a (set of) thumbnailer programs. Imagemagick can create thumbnails for pdfs. Using a thunbnailer program will not work before the file is actually uploaded (the html5 file preview functionality is not even able to autorotate based on exif, to my knowledge).
