Free icons?

I’m adding icons to my app, mainly because the menus actually have quite a few options now so icons make the whole thing more readable. So far i’m just using the Swing l&f icons that Sun makes avalible (handy open/save/new icons for a start) but theres not that many that are actually usable. Most of my current ones are done pixel by pixel myself which unfortunatly makes them pretty inconsistant.

Are there any free icon resources out there? I’m using 24x24 for menus and 22x22 for JTree labels. One thing that i miss from win32 programming is that there isn’t the huge range of standard icons avalible :frowning:

What about those from the NetBeans project e.g.?
Or Eclipse?

A good idea, but i can’t figure out what the license for Eclipse lets you do with their icons. It seems like all resources are covered by the same as the source, and that you’re allowed to use them for your own use… At least thats my interpretation on their lengthy licensing docs. Does this sound about correct?

There are a couple of good hits on Google for public domain icons:

But this is pretty much the eternal question. Good development graphics resources, anyone?

Eclipse uses a very nice and consistent set of icons you can use under a liberal license [1]. Ximian created a huge set (more than 1000) of icons [2] for their version of OpenOffice and publish them under the LGPL. They fit other Gnome/GTK icons [3], for example those of Evolution (but those have a GPL license IIRC).

Sun has a set of icons for use in Java programs:

KDE has some icons sets too you can download of their themes page.
