Site that provides mimetype icons for hotlinking
This site simply hosts icons for lots of filetypes that you can use and link to.
You can use a file extention like /html, a filename like /movie.avi, a mimetype
like /application/pdf .
You can also use the ?size=16 to get a consistent size of icons, and the ?default= to force a default instead of an HTTP 404.
Thanks to Faenza Icon Set team for the gorgeous icon set!
Thanks to Paul Tarjan and Jeff Lindsay for idea of stdicon
