Instability detected in the image when hovering over and off

Here is a snippet of code from my HTML file:

<img id="id1" src="photo1" usemap="#ir" >
<img  src="photo2" id="id2"/>
<span>
<map name="ir" id="ir">    
<area alt="" title="my title" href="my link" shape="poly" coords="13,15,29,34,10,65,1,39,17,57,357,77,15,64" />    
</map>       
</span>  

In addition to this code, I have applied some CSS styling:

#id2 {display: none; opacity: 0.4;}

And here's the JQuery code for this part:

    $(document).ready(function() {
$('span').on('mouseover',function() {
    $('#id2').show();
}).on('mouseleave',function() {
    $('#id2').hide();
});
})  

However, when attempting to hover over the designated image area to reveal a different photo with reduced opacity, I encountered issues.
The secondary photo display was not consistent and the hyperlink functionality was unreliable.
It seems that the image swapping and linking functions are not synchronizing properly, only working sequentially rather than simultaneously.

If I'm getting your meaning correctly, consider utilizing mouseenter/mouseleave instead and implement a hover event that covers both actions.

$(document).ready(function() {
  var $img = $('#id2');
 $('span').hover(function() {
   $img.show();
 },function() {
   $img.hide();
});

In contrast to mouseover, the corresponding event for it is mouseout (not mouselave), while mouseleave is the opposite of the mouseenter event.

The key distinction between these two approaches is that mouseenter/mouseleave events do not bubble up, whereas mouseover/mouseout events do.

Additionally, when using mouseover/mouseout on an element containing child elements, moving the mouse over a child element can trigger the parent's mouseout event. This may create the illusion that the mouse has exited the parent element when in fact it has simply moved into a child element.
