Creating an UIImage from a URL

A question came up over the weekend as to download an image off the internet and add it to a UIImage object on the iPhone. The answer is to create an NSData object that grabs the contents of the URL and then initialize the image with that data, as such:

id path = @"http://merrimusings.mu.nu/archives/images/groundhog2.jpg";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data cache:NO];
