Pass the image id to a function and show/hide();
<p>I've four images with IDs img01, img02, img03, img04.</p>

<p>Another four images are added to an array to show that they are related to each image mentioned above, like IDs hover01, hover02, hover03, hover04.</p>

<p>How to write a common function to show the hover image related to each? That is, each time when the mouse is over an image, an argument should be passed to a function to show. </p>

<p>Hope that makes sense.</p>
