    Intelligent Media Management:CreateImageModerationTask

    Last Updated:Jan 28, 2026

    Detects non-compliant content in images, such as pornography, terrorism, undesirable scenes, logos, and text-in-image violations.

    Operation description

    • Before you use this operation, make sure that you understand the billing methods and pricing of Intelligent Media Management.
      Important The execution time of asynchronous tasks is not guaranteed.
    • Image requirements:

      • Image URLs support the HTTP and HTTPS protocols.

      • The following image formats are supported: PNG, JPG, JPEG, BMP, GIF, and WEBP.

      • The image size cannot exceed 20 MB for both synchronous and asynchronous invocations. The height or width cannot exceed 30,000 pixels, and the total number of pixels cannot exceed 250 million. For GIF images, the total number of pixels cannot exceed 4,194,304, and the height or width cannot exceed 30,000 pixels.

      • The image download timeout period is 3 seconds. If the download takes longer than 3 seconds, a timeout error is returned.

      • For best results, the image resolution should be at least 256 × 256 pixels. Low resolution may affect detection accuracy.

      • The response time for image detection depends on the image download time. Ensure the storage service where the image is stored is stable and reliable. Use Alibaba Cloud Object Storage Service (OSS) or CDN.

    • This is an asynchronous operation. After a task starts, its information is saved for only 7 days. You cannot query the information after this period. To view task information, you can call the GetTask or ListTasks operation and use the returned TaskId. Alternatively, you can set the Notification parameter to receive task information through asynchronous notification messages.

    Note

    The detection results are returned in an asynchronous notification message. The Suggestion field in the message has one of the following values:

    • pass: The image passed the review. No non-compliant content was detected.

    • block: The image failed the review. Non-compliant content was detected. The Categories field indicates the non-compliant category. For more information about the categories, see Content Moderation detection results.

    • review: The image requires manual review. After the manual review is complete, another asynchronous notification message is sent to inform you of the result.

    RAM authorization

    The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

    • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

    • API: The API that you can call to perform the action.

    • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

    • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

      • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

      • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

    • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

    • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
