Answer 1

i think you need to use ASIHTTP request which use to Asynchronous call to server and multiple images stores on to the server.

For that implementation of that method after this method use to upload the images.

- (IBAction)btnPostImages_Clicked:(id)sender {

     if ([arrImages count] > 0) {
               NSString *strURL = @"Write Your URL Here.";
               ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:strURL]];
               [request setDelegate:self];
               [request setPostValue:@"This is sample text..." forKey:@"text"];
               for (int i = 0; i < [arrImages count]; i++) {
                         [request addData:[arrImages objectAtIndex:i] withFileName:@"image.jpg" andContentType:@"image/jpeg" forKey:[NSString stringWithFormat:@"image%d", i + 1]];
               }
[request startAsynchronous];
     }
     else {
              UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Message" message:@"Please select images..." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alertView show];
            [alertView release];
    }
}
