If you are insistent on using images instead of buttons you can use Gesture Recognizer. Create an imageView and enable its userInteraction

UIImageView *testImageView              =   [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"someImage"]];
testImageView.frame                     =   CGRectMake(30.0,30.0,60.0,40.0);
testImageView.tag                       =   30;
testImageView.userInteractionEnabled    =   TRUE;
[tempPlotView addSubview: testImageView];
[testImageView release];    

Now allocate a gesture Recognizer object and add it to your imageView...

UITapGestureRecognizer *testGesture =   [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singletap:)];
[testGesture setNumberOfTapsRequired:1];
[testImageView addGestureRecognizer: testGesture];
[testGesture     release];

Now in the selector "singleTap" you can do whatever your action is..

-(void)singleTap:(UIImageView*)sender{
    if(sender.tag == 30){
        //do your stuff here...
    }
}

Hope this help...cheers....
