iphone image. multiple touches/drag.

Question

The problem im facing rightnow is that in an above portion i have scrollview which have different images clicking on it will clone a same image on to the screen. i have enable touches so i can drag it, but when i clicked another image and it comes to the screen i can drag that anotther image but not the previous one now. can any one have a solution so i can drag multiple images on clicking on it. i can put 4-5 on it for my use.

i have use this code: Code:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{ 
    UITouch *touch=[[event allTouches]anyObject];
    CGPoint location = [touch locationInView:touch.view];
    g1.center = location;    
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{     
    [self touchesBegan:touches withEvent:event];
}

thanks in advance.
