/* style image used trigger modal */  #myimg {      border-radius: 5px;      cursor: pointer;      transition: 0.3s;  }    #myimg:hover {opacity: 0.7;}    /* modal (background) */  .modal {      display: none; /* hidden default */      position: fixed; /* stay in place */      z-index: 1; /* sit on top */      padding-top: 100px; /* location of box */      left: 0;      top: 0;      width: 100%; /* full width */      height: 100%; /* full height */      overflow: auto; /* enable scroll if needed */      background-color: rgb(0,0,0); /* fallback color */      background-color: rgba(0,0,0,0.9); /* black w/ opacity */  }    /* modal content (image) */  .modal-content {      margin: auto;      display: block;      width: 80%;      max-width: 700px;  }    /* caption of modal image (image text) - same width image */  #caption {      margin: auto;      display: block;      width: 80%;      max-width: 700px;      text-align: center;      color: #ccc;      padding: 10px 0;      height: 150px;  }    /* add animation - zoom in modal */  .modal-content, #caption {       -webkit-animation-name: zoom;      -webkit-animation-duration: 0.6s;      animation-name: zoom;      animation-duration: 0.6s;  }    @-webkit-keyframes zoom {      {-webkit-transform:scale(0)}       {-webkit-transform:scale(1)}  }    @keyframes zoom {      {transform:scale(0)}       {transform:scale(1)}  }    /* close button */  .close {      position: absolute;      top: 15px;      right: 35px;      color: #f1f1f1;      font-size: 40px;      font-weight: bold;      transition: 0.3s;  }    .close:hover,  .close:focus {      color: #bbb;      text-decoration: none;      cursor: pointer;  }    /* 100% image width on smaller screens */  @media screen , (max-width: 700px){      .modal-content {          width: 100%;      }  }
<!-- trigger modal -->  <img id="myimg" src="img_fjords.jpg" alt="trolltunga, norway" width="300" height="200">    <!-- modal -->  <div id="mymodal" class="modal">      <!-- close button -->    <span class="close" onclick="document.getelementbyid('mymodal').style.display='none'">&times;</span>      <!-- modal content (the image) -->    <img class="modal-content" id="img01">      <!-- modal caption (image text) -->    <div id="caption"></div>  </div>

it work fine 1 image.

on site have pages need show more image, , if set code other image, popup work first , not other images.
