1. string 2. VisualFeatureTypes.Description 3. results.Description.Captions[0] https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-describing-images#use-the-api The image description feature is part of the Analyze Image API. You can call this API through a native SDK or through REST calls. Include Description in the visualFeatures query parameter. Then, when you get the full JSON response, parse the string for the contents of the "description" section.

the correct choice between Stream and string depends on the source of the image: If you have the image file and want to upload it directly from the client or server where the request is being made, you should use a Stream. This approach is direct and efficient for handling binary data without the need for encoding or hosting the image externally. If the image is already hosted online and accessible via a URL, you use a string containing the URL to let the API fetch the image for analysis.

Yes given the previous questions answers, the files are uploaded in blob storage. So string is the correct answer

Microsoft employees has bad naming convention. So they try to trick you with that. String image? Nope, I will not write it but it should have been String imageUrl. Who wants to remember these api calls in this age of copilots (ignore google and documentations).
