How to click some parts of an image
<p>I need to make an index page only with the following image. </p>

<p>When the user clicks the water between the flags, he can continue to the next page. If the user presses at any other location, an alert message will be shown. Do we have any x-axis,y-axis concept in PHP? </p>

<p>Anyone have any idea how to make an image's some parts clickable? Anyone can provide me examples or links to documents?</p>

<p>Thanks!</p>
