Compared to DropIcon 3.0.2 this one creates beautiful anti-aliased icons! An update would certainly be nice, it's been literally years but this is still a gem. My only complaint is that every now and then an icon fails to update in the finder. other than that 5/5 super super super program. I've tried nearly all of them and this is the best combined with quicksilver! drag and drop away! i'm actually creating 10,000 icons as I type this in the background for my images!
And if you want an even cooler solution combine quicksilver with Pic2Icon and Xee 2.0 as your default image browser! Sweetness!
