Ah, thanks so much. I'm not too artistically inclined so I've got to rely on the share and share alike approach to amass an icon collection. Too bad it's only in 128; I wish there was an easy way to upscale some of these good looking icons to 512 to "future-proof" them, so to speak.
You rely can't upscale...or downscale for that matter with any sort of professional looking results. A true icon has to be redrawn in each of the smaller sizes, so even starting in 512 and shrinking the image is going to yield mixed results depending on the complexity of the icon. I wish I had it in true icns but I'm not sure if it even exists, I've only seen it in a png.
and FWIW, I'm not artistically inclined in the least either
