UIImage from URL difficulty

The following code works to load a UIImage from a URL. However, when I try to load an image from Craigslist, the image does not work. I have verified the craigslist imagePath is working.

NSURL *imageURL = [NSURL URLWithString:@"http://images.free-extras.com/pics/c/car-530.jpg"];
NSData *data = [NSData dataWithContentsOfURL:imageURL];
UIImage *img = [[UIImage alloc] initWithData:data] ;
self.imageView.image = img;

I have tried this

NSURL *imageURL = [NSURL URLWithString:@"http://images.craigslist.org/3m23pb3l85T65R05S4b8462d2236c156a1ce3.jpg"];
NSData *data = [NSData dataWithContentsOfURL:imageURL];
UIImage *img = [[UIImage alloc] initWithData:data] ;
self.imageView.image = img;

and even this

NSString * urlString开发者_运维知识库 = [@"http://images.craigslist.org/3m23pb3l85T65R05S4b8462d2236c156a1ce3.jpg" stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSURL * imageURL = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:imageURL];
UIImage *img = [[UIImage alloc] initWithData:data] ;
self.imageView.image = img;

Any help is much appreciated. My Error message reads:

Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)

have you checked if the data and the probably evolving image structure are not nil? Normally this should not happen, but it might be valuable to point out what went wrong.

The loading code looks good to me - I use something similar.

you can try

imageView.image = img;

instead of

self.imageView.image = img;
