Im kinda new to GridView, how to load images from NSDocumentDirectory, here is how I save them:

            NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory,    NSUserDomainMask ,YES );
            NSString *documentsDir = [paths objectAtIndex:0];
            NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"oneSlotImages%d.png", i]];


                    ALAssetRepresentation *rep = [[info objectAtIndex: i] defaultRepresentation];
                    UIImage *image = [UIImage imageWithCGImage:[rep fullResolutionImage]];

                    //----resize the images
                    image = [self imageByScalingAndCroppingForSize:image toSize:CGSizeMake(256,256*image.size.height/image.size.width)];

                    NSData *imageData = UIImagePNGRepresentation(image);
                    [imageData writeToFile:savedImagePath atomically:YES ];

and can this have an option, to for example if an image is deleted will retain it, and if one image is deleted will return the old one?
