在此示例中，在第60行的popup.js中， https://ajax.googleapis.com/ajax/services/search/images 。这现在已过期。

您可以通过提供查询参数进行验证。例如，
https://ajax.googleapis.com/ ajax / services / search / images？v = 1.0& q = chrome 将会回应这个API不再可用。

Is this tutorial still ok? I've downloaded all metioned files and the extension is not working. I think there is a problem connected with Ajax request.

I got the message:

Cannot display image. No response from Google Image..

I tried to perform Ajax request to another website, but it turned out that the request is performed locally - despite of permissions in a menifest.json file.

In this example, inside popup.js at line 60, a call is made to https://ajax.googleapis.com/ajax/services/search/images. This is now expired.

You can verify by providing a query argument. For example, https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=chrome will give response "This API is no longer available.".
