One thing you can do for highlight the image when you touch on it. When you touch on image you should change the alpha of selected image in touch began method and reset the image alpha in touch ended method. So its look like button.

For Ex.

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [[event allTouches] anyObject];
    CGPoint location= [touch locationInView:self.view];
    if(CGRectContainsPoint(firstImage.frame, location)) 
    {
        //  flag like
        select=1;        
        firstImage.alpha = 0.5;
    }
    else if(CGRectContainsPoint(secImage.frame, location))
    {
        select=2;        
        secImage.alpha = 0.5;
    }
    [mComment resignFirstResponder];

}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { 

    UITouch  *touch = [[event allTouches] anyObject]; 
    CGPoint location = [touch locationInView:self.view];

    if(CGRectContainsPoint(firstImage.frame, location)) {   
        if(select==1) {
            firstImage.alpha = 1.0;
            var=1;
        }}
    else if(CGRectContainsPoint(secImage.frame, location))  { 

        if(select==2) {
            secImage.alpha = 1.0;
            vars=1;
        }}
    select=0; 
}
