	UIView * view = [[UIView alloc] initWithFrame:CGRectMake( 0.0f, 0.0f, kAffirmationThumbnailWidth, kAffirmationThumbnailHeight )];
	view.backgroundColor = [UIColor grayColor];
	UIImageView * imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, kAffirmationThumbnailWidth, kAffirmationThumbnailHeight)];
	imageView.backgroundColor = [UIColor clearColor];
	imageView.alpha = 1.0;
	[view addSubview:imageView];

	// Background getting of small image and loading into memory
	dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
	NSString * imagePathSmall = [NSString stringWithFormat:@"%@_small.jpg",[[affirmation imagePath] stringByDeletingPathExtension]];
