Save images for later use in iPhone

I want to save images that user selects from the camera roll, when app exits and restart i want to show those images to user. I have searched over internet and not found much useful resource. I know I can write the image in database as blob but I dont want to do it as increases the database size.
Is it possible to save the image path and then later use that path to access that image.

Save the Image into the DocumentDirectory

NSString *imageName = "myImage.png";
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,  NSUserDomainMask, YES);
NSString * documentsDirectoryPath = [paths objectAtIndex:0];

NSString *dataPath = [documentsDirectoryPath  stringByAppendingPathComponent:imageName];
NSData* settingsData = UIImagePNGRepresentation(imageData);

[settingsData writeToFile:dataPath atomically:YES];

EDIT:

If you want to see your saved images on the iPhone/iPad (or share them) in iTunes->Apps->Documents jut add in Info.plist "Application supports iTunes file sharing" : "YES"

You have to use UIImagePickerController to get the media from the Camera roll

You will get the image in the delegate method 

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

Here you can get the image and save is as NSData .. in a file and then retrieve back it next time

Edit :

to Save

    Data = UIImageJPEGRepresentation(theImage,1.0);

       NSString  *imagePath = [ContentFolder stringByAppendingPathComponent:[NSString stringWithFormat:@" %d.plist",Counter]];
        NSLog(@" iamge path %@",imagePath);


        NSMutableDictionary *objectDictionary = [[NSMutableDictionary alloc]initWithObjectsAndKeys:data,@"data", nil];

        [objectDictionary writeToFile:imagePath atomically:YES];

you should be able to change these according to your needs..
