Answer 1

you can Convert Your image in ti NSData like:-

if PNG image

UIImage *image = [UIImage imageNamed:@"imageName.png"];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];

if JPG image

UIImage *image = [UIImage imageNamed:@"imageName.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);

and you can store it in to CoreData may be like this way is usefull for you:-

[newManagedObject setValue:imageData forKey:@"image"];

You can load like :-

 NSManagedObject *selectedObject = [[self yourFetchCOntroller] objectAtIndexPath:indexPath];
      UIImage *image = [UIImage imageWithData:[selectedObject valueForKey:@"image"]];
// and set this image in to your image View  
    yourimageView.image=image;
