Parameters for an image URL that uses POST

If you enable this policy, it specifies the parameters used when an image search that uses POST is performed. The policy consists of comma-separated name/value pairs. If a value is a template parameter, like {imageThumbnail} in the preceding example, it's replaced with real image thumbnail data. This policy is applied only if you enable the 'DefaultSearchProviderEnabled' (Enable the default search provider) and 'DefaultSearchProviderSearchURL' (Default search provider search URL) policies. Specify Bing's Image Search URL Post Params as: 'imageBin={google:imageThumbnailBase64}'. Specify Google's Image Search URL Post Params as: 'encoded_image={google:imageThumbnail},image_url={google:imageURL},sbisrc={google:imageSearchSource},original_width={google:imageOriginalWidth},original_height={google:imageOriginalHeight}'. If you don't set this policy, image search requests are sent using the GET method. Starting in Microsoft Edge 84, you can set this policy as a recommended policy. If the user set a default search provider, the default search provider configured by this recommended policy can't be added to the list of search providers the user can choose from. If this is the desired behavior, use the 'ManagedSearchEngines' (Manage Search Engines) policy. Example value: content={imageThumbnail},url={imageURL},sbisrc={SearchSource}
