How to Define Placeholder Image for Missing Images

If our crawler cannot find images for indexing from your web page, you can replace the default placeholder thumbnail image with your own image.

Instructions

To define your own placeholder image, add the following CSS rule to your website’s stylesheet:

span.main-image.noimage {
  background-image: url("https://www.yourdomain.com/yourimage.png") !important;
  background-repeat: no-repeat !important;
  background-size: contain !important;
}

or this one if you prefer inlined image (png), encoded in base64:

span.main-image.noimage {
  background-image: "url('data:image/png;base64,your-encoded-image')" !important;
  background-repeat: no-repeat !important;
  background-size: contain !important;
}
