Photo by bas:ilSo, we have a website that displays images from an external source based upon a URL. For various reasons, sometimes the external source does not have a valid image for the request. In order not to show a broken image to the use, we need to validate that the image is valid.

Thanks to Google (NOT Bing. haha) we found a great little approach that was quickly placed into a Drupal template file.

if (@GetImageSize("http://www.testdomain.com/testimage.gif")) {
  echo "image exists";
} else {
  echo "image does not exist";
}

And according to the site, if you do not have GD installed you can try this code:

if (@fclose(@fopen("http://www.testdomain.com/testimage.gif", "r"))) {
  echo "image exists";
} else {
  echo "image does not exist";
}

We took the concept of the GetImageSize function to handily render web thumb shots from an external service, only if a valid image exists. This way we don’t show broken images to those Internet Explorer users.
