You should load the image in the background or the view will freeze. Try this:

UIImage *img = [[UIImage alloc] init];

dispatch_async(dispatch_get_global_queue(0,0), ^{

    NSData * data = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:@"http://www.test.com/test.png"];
    img = [UIImage imageWithData: data];

     dispatch_async(dispatch_get_main_queue(), ^{
        //PUT THE img INTO THE UIImageView (imgView for example)
        imgView.image = img;
     });
});
