where to download standard word powerpoint excel icons

Question

I'm working on a web app that has functionality to export different data -- for instance in excel format.

Where do I find the standard icons for Excel, Word, Powerpoint (and perhaps csv) files

I'd like them to be directly downloadable in different sizes (at least 16x16 and 24x24). And preferably in png format (icon format is no good for using in a web app)

Answer 1

Try http://www.iconfinder.net/

Answer 2

Famfamfam's Silk icon set has some nice little app icons: www.famfamfam.com/lab/icons/silk/

They're only 16x16 but they're very clean... and there's over 1000 of them so you can get a unified style to the whole app by using them elsewhere.
