          public ImageInfo preloadImage(java.lang.String uri,

      "Preloads" an image, i.e. indentifies whether the source image is supported by this implementation and determines the image's intrinsic size and possibly some additional information. The image is usually not fully loaded at this time to conserve memory. The method returns null if the image was not identified. An `ImageException` is only thrown if the image is identified but some error has happened while working on the file.
      Parameters:
        `uri` - the original (unresolved) URI of the image
        `src` - a image source the image is loaded from
        `context` - the context object that provides configuration information
      Returns:
        an image info object with the basic information about an image or null if the image is not supported by this implementation
      Throws:
        `java.io.IOException` - if an I/O error occurs while preloading the image
