Answer 1

@Nezar ElKhuffash The URL used in the request "http://example.com/images/test.jpg" is not a valid URL with an image. You could try a different URL, for example the following JPG image which is directly available from wikipedia website.

https://upload.wikimedia.org/wikipedia/commons/thumb/1/12/Broadway_and_Times_Square_by_night.jpg/450px-Broadway_and_Times_Square_by_night.jpg

Please ensure the image URL is not behind a CDN as those links cannot be accessed by the API to run the operation.
