@Javi Guarin If you have passed a request programmatically then there is no option to display the preview of image passed to the service, it will only send the response depending on how the image is processed.
The analyze image API uses either the URL of the image or stream, if you use URL of image, you can see the preview by loading the URL separately. If you use stream, you will have to build the image from stream that was passed in request body.
If you are able to download the same image taken from this source, you can upload it through vision studio and check if there is any preview seen. Vision studio provides a preview of image before you submit the image, the final response though is still based on how the service Api sees the request body. Thanks!!
