Store image from UIImagePickerController in iPhone?

Question

I have tried to store image (NSUserDefault) from UIImagePickerController in iPhone.

This way to stored image:

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *originalImage=[info objectForKey:UIImagePickerControllerOriginalImage];
    NSData * imageData = UIImagePNGRepresentation(originalImage);
    NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
    [user setValue:imageData forKey:@"pictureData"];
}

This way to retrieve image:

NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
UIImage *myImage = [UIImage imageWithData:[user valueForKey:@"pictureData"]];
[btn2 setImage:myImage forState:UIControlStateNormal];

When i retrieve the image from NSUserDefaults to set UIButton, finally the image shown, but the direction changes from bottom to right, How to fix this issue? Please help me

Use UIImageJPEGRepresentation to store an image into NSUserDefaults this way:

NSData * imageData = UIImageJPEGRepresentation(originalImage, 90);
NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
[user setValue:imageData forKey:@"pictureData"];
