You can use "AsyncImageView" class files it will load image synchronically.

please refer

in this answer this method call for tableview you can use in for loop and place imageview in scrollview for putting images vertically

int y = 10; 
for (int i = 0; i < (number of images); i++)
{
   UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(X, y, width, height)];

   NSString *imageURL = [NSString stringWithFormat: (image link for i number)];
   AsyncImageView *async = [[AsyncImageView alloc]initWithFrame:CGRectMake(0, 0, width, height)];
   [async loadImageFromURL:[NSURL URLWithString:imageURL]];
  [imageView addSubview:async];
  [scrollView addSubview:imageView];
  y = y+height+10;
}

use for loop and use code from "UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(X, y, width, height)];" – Pratik Mar 15 '13 at 05:03
to [cell addSubview:imageView]; and also replace cell to scrollview – Pratik Mar 15 '13 at 05:04
why use AsyncImageView in ScrollView ? it load only one time,if we use cell means it load more? – NANNAV Mar 15 '13 at 05:13
Please explain clearly about what is (image link for i number) of your code? – Sovannarith Mar 15 '13 at 07:08
this is image link of your image if i = 0 then first image link and i=1 then second image link. – Pratik Mar 15 '13 at 07:12

You can user PSTCollectionView for gridView kind of display and SDWebImage for lazy loading.

Are you asking how to load remote images OR how to layout them on a scroll view?

1.
UIImage * image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"..."]]];
Wrap it all in dispatch_async or put it in NSOperation to make sure you don't block the main thread.

2.
You can try to use UIPageViewController instead of a UIScrollView
