Image within an Image using HTML, CSS and JavaScript -


i created regular image in html. then, dynamically via javascript, added image within initial image. however, having issue if user zoom in or out, internal image not stay in same place. , possible user zoom in case, anytime, , need internal image not move. not have fancy, , trying sorts of ways work, if have way uses html , css, add code, because have tried many different avenues , changed html around multiple times. however, if code, in depth, glad supply you. appreciated, or if need more clarification, can well, in advance.

here example of code adds image image, , has issue explained above:

$(document).ready(function() {      $('#myimgid').click(function(e) {        var offx = event.clientx;      var offy = event.clienty;        margin = 20;        if (offx > margin) offx -= margin;      if (offy > margin) offy -= margin;        var signhereimage = document.createelement("img");        signhereimage.setattribute('src', 'imageinserted.jpg');      signhereimage.setattribute('class', 'overlays');      signhereimage.style.left = offx + "px";      signhereimage.style.top = offy + "px";        document.body.appendchild(signhereimage);      });  });
<form id="form1" runat="server">    <div>      <img src="page3.jpg" alt="pdf image" id="myimgid" />    </div>  </form>

this part is, know doing incorrectly, not know certain, again in advance.

i use background-image property achieve this. can place image in div, give div background image, , position image relative div. here's working example:

div {    position: relative;    height: 500px;    background-image: url(https://images.unsplash.com/photo-1413781892741-08a142b23dfe?dpr=2&auto=format&fit=crop&w=1500&h=1000&q=80&cs=tinysrgb&crop=&bg=);    background-size: cover;  }    img {    position: absolute;    margin: auto;    top: 0;    bottom: 0;    right: 0;    left: 0;    width: 200px;  }
<div>    <img alt="img" src="https://images.unsplash.com/photo-1483086431886-3590a88317fe?dpr=2&auto=format&fit=crop&w=1500&h=2247&q=80&cs=tinysrgb&crop=&bg=" />  </div>
