MmmVomit Posted October 5, 2007 Share Posted October 5, 2007 I wouldn't say any one function is better than another. One's a hammer, another's a screwdriver. Niether is better than the other, they're just suited to different jobs. If you tell us what you'd like to actually DO with an image, then maybe we can help you.
