Question

CSS:

.posting-logo-div {
}
.posting-logo-img {
  height: 120px;
  width: 120px;
}
.posting-photo-div {
  height: 5px;
  width: 5px;
  position: relative;
  top: -140px;
  left: 648px;
}
.posting-photo-img {
  height: 240px;
  width: 240px;
}

HTML:

<div id="image" class="posting-logo-div">
  <img
    src="../images/some-logo1.jpg"
    onerror="this.src='../images/no-logo-120.jpg';"
    class="posting-logo-img"
  />
</div>
<div id="photo" class="posting-photo-div">
  <img
    src="../images/some-logo2.jpg"
    onerror="this.src='../images/no-logo-240.jpg';"
    class="posting-photo-img"
  />
</div>

This doesn’t seem to work in Chrome or Mozilla but does work in IE.

This works:

<img src="invalid_link"
     onerror="this.onerror=null;this.src='https://placeimg.com/200/300/animals';"

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the “error” event again which will result in an infinite loop. We can guard against this by simply nullifying the “error” handler via this.onerror=null;.
