Objective-c – Save UIImage, Load it in Wrong Orientation

I am using the following code to save and load images that I pick from either the library or take using the camera:

//saving an image
- (void)saveImage:(UIImage*)image:(NSString*)imageName {
    NSData *imageData = UIImagePNGRepresentation(image); //convert image into .png format.
    NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it
    NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory
    NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]]; //add our image to the path
    [fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image)
    NSLog(@"image saved");
}

//loading an image
- (UIImage*)loadImage:(NSString*)imageName {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]];
    return [UIImage imageWithContentsOfFile:fullPath];
}

This is how I set the picked image to be shown in my UIImageView:

imgView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

However, when I pick and image and set it to be shown in my UIImageView it is fine, but when I load that image it often is the wrong orientation. Any ideas? Anyone experienced this or know how I could resolve this?

Thanks.

EDIT:

So it seems, if you load a photo which was taken a photo in portrait upside-down, it loads in that orientation, if you take a photo in landscape left it loads in that orientation. Any ideas how to get around this? Whatever orientation they load it they always return as UIImageOrientationUp.
