You could do an advanced image search with google, the icon size you need to find is 84x84.
I don't even worry about size when looking for a picture to use as an icon, the system will resize it automatically. Just figured out how the custom shortcuts thing works, so making new shortcuts on my desktop with red/black icons. I downloaded a theme and some icon packs, but there isn't an icon for everything, so I'm fixing the rest myself!
The only drawback with not picking the right size is that if they are too small they will look bad when the system re-sizes them.
OK, you got me, that is true, blowing up small stuff never looks good. So far I haven't had problems finding stuff over 200x200 to use, and that stuff will look fine shrunk down.
