The net has permissively licenses media... it just takes some looking to find useful works free in the libre sense rather than just no-cost. This section has resources I've found helpful in my projects. If the license matter in your work then double check that I'm right before using it.
Here are a few things the site offers links and downloads
- Icons are a vital part of making a nice and intuitive looking user interface. Hence it shouldn't be any surprise that there's numerous free sets available for software and web developers. This section is largely thanks to Max Power and Gnome Art where many of these sets were found.
- Fonts: From the professional to the abstract, fonts can be a handy resource for banners and specialized labels. For a more extensive listing also, see Vitaly Friedman's compilation of the 25 Best Free Quality Fonts.
- Audio: Though not commonly a consideration, music and sound effects can be handy for some projects (most often games).
