NSMutableArray *arr=[[NSMutableArray alloc] init];
NSString *urlString=[NSString stringWithFormat:#"http://ielmo.xtreemhost.com/array.php"];
NSURL * url=[NSURL URLWithString:urlString];
NSData *data =[NSData dataWithContentsOfURL:url];
NSError *error;
NSMutableArray *json=(NSMutableArray*)[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"%d",[json count]);
NSLog(#"%#",[json objectAtIndex:0]);
NSString *imageString;
for (int i=0; i<[json count]; i++) {
imageString=[NSString stringWithFormat:#"%#",[json objectAtIndex:i]];
[arr addObject:imageString];
}
NSLog(#"%#",arr);
// NSString *imageString=[NSString stringWithFormat:#"%#",[json objectAtIndex:0]];
NSURL * urlone=[NSURL URLWithString:imageString];
NSData *datanew =[NSData dataWithContentsOfURL:urlone];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];
[imageView setImage:[UIImage imageWithData:datanew]];
UIView * testView = [[UIView alloc] initWithFrame:CGRectMake(30.0f, 300.0f, 300.0f, 200.0f)];
[testView addSubview:imageView];
[self.view addSubview:testView];

After parsing JSON response use follow code
UIScrollView *testView = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320,480)];
for(int i=0; i<[json count]; i++){
NSLog(#"%#",[json objectAtIndex:i]);
NSString *imageString=[NSString stringWithFormat:#"%#",[json objectAtIndex:i]];
NSURL * urlone=[NSURL URLWithString:imageString];
NSData *datanew =[NSData dataWithContentsOfURL:urlone];*
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,i*480,320,480)];
[imageView setImage:[UIImage imageWithData:datanew]];
[testView addSubview:imageView];
}
[self.view addSubView:testView];
*Note: Now you are going with Synchronous Request to download & load images in the view. It is not a good approach. Use Asynchronous requests for downloading images and loading them.
Find the following URL for asynchronous image downloading

you can get an image dictionary into array like this, into data object
Suppose i have PostClubDC class with posDC obj
for(NSDictionary *returnDicto in dataArray)
{
PostClubDC *postDC = [[PostClubDC alloc] init];
NSDictionary * returnDict = [returnDicto objectForKey:#"club_info"] ;
postDC.postID = [[returnDict objectForKey:#"Id"]integerValue];
postDC.postName = [returnDict objectForKey:#"name"];
postDC.postImage = [returnDict objectForKey:#"image"];
[yourDataArray addObject:postDC];
}
