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
