# GetImageHashImage

Returns the training image associated with an image hash.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the image hash. | Yes
`format` | The image format to use for the returned image. `bmp` `gif` `jpeg` `pdf` `png` `ppm` `tiff` `webp` If you do not specify a format, but specify a file name with the `FileName` parameter, Media Server returns the image in a format that matches the file extension. If you do not specify a format or a file name, the image is returned in its original format. | No
`identifier` | The identifier of the image hash for which you want to retrieve the image. | Yes
`imagesize` | The maximum dimensions to use for the returned image, in pixels, width followed by height. If you set the width and height, for example `200x300`, Media Server returns the largest image that fits within the specified size and maintains the original aspect ratio. To specify a maximum width or maximum height, specify that dimension and set the other to zero. For example, `250x0` always returns an image 250 pixels wide. If you do not specify a size, Media Server returns the image at its original size. | No

You can also set the parameters Output and FileName to write the output of this action to a file.

## Example

    curl http://localhost:14000/action=GetImageHashImage
                                -F database=ImageHashes
                                -F identifier=AnImage
                                -o ReturnedImage.png

## Response

The response contains the image data.

Media Server identifies the image type and sets the `Content-Type` header to the appropriate MIME type. The `Content-Length` header is set to the length of the image data in bytes.

If an error occurs, Media Server returns a standard XML error response.
