          layer
              Specifies whether images are drawn below or above
              traces. When `xref` and `yref` are both set to `paper`,
              image is drawn below the entire plot area.
          name
              When used in a template, named items are created in the
              output figure in addition to any items the figure
              already has in this array. You can modify these items
              in the output figure by making your own item with
              `templateitemname` matching this `name` alongside your
              modifications (including `visible: false` or `enabled:
              false` to hide it). Has no effect outside of a
              template.
          opacity
              Sets the opacity of the image.
          sizex
              Sets the image container size horizontally. The image
              will be sized based on the `position` value. When
              `xref` is set to `paper`, units are sized relative to
              the plot width. When `xref` ends with ` domain`, units
              are sized relative to the axis width.
          sizey
              Sets the image container size vertically. The image
              will be sized based on the `position` value. When
              `yref` is set to `paper`, units are sized relative to
              the plot height. When `yref` ends with ` domain`, units
              are sized relative to the axis height.
          sizing
              Specifies which dimension of the image to constrain.
          source
              Specifies the URL of the image to be used. The URL must
              be accessible from the domain where the plot code is
              run, and can be either relative or absolute.
          templateitemname
              Used to refer to a named item in this array in the
              template. Named items from the template will be created
              even without a matching item in the input figure, but
              you can modify one by making an item with
              `templateitemname` matching its `name`, alongside your
              modifications (including `visible: false` or `enabled:
              false` to hide it). If there is no template or no
              matching item, this item will be hidden unless you
              explicitly show it with `visible: true`.
          visible
              Determines whether or not this image is visible.
          x
              Sets the image's x position. When `xref` is set to
              `paper`, units are sized relative to the plot height.
              See `xref` for more info
          xanchor
              Sets the anchor for the x position
          xref
              Sets the images's x coordinate axis. If set to a x axis
              id (e.g. "x" or "x2"), the `x` position refers to a x
              coordinate. If set to "paper", the `x` position refers
              to the distance from the left of the plotting area in
              normalized coordinates where 0 (1) corresponds to the
              left (right). If set to a x axis ID followed by
              "domain" (separated by a space), the position behaves
              like for "paper", but refers to the distance in
              fractions of the domain length from the left of the
              domain of that axis: e.g., *x2 domain* refers to the
              domain of the second x  axis and a x position of 0.5
              refers to the point between the left and the right of
              the domain of the second x axis.
          y
              Sets the image's y position. When `yref` is set to
              `paper`, units are sized relative to the plot height.
              See `yref` for more info
          yanchor
              Sets the anchor for the y position.
          yref
              Sets the images's y coordinate axis. If set to a y axis
              id (e.g. "y" or "y2"), the `y` position refers to a y
              coordinate. If set to "paper", the `y` position refers
              to the distance from the bottom of the plotting area in
              normalized coordinates where 0 (1) corresponds to the
              bottom (top). If set to a y axis ID followed by
              "domain" (separated by a space), the position behaves
              like for "paper", but refers to the distance in
              fractions of the domain length from the bottom of the
              domain of that axis: e.g., *y2 domain* refers to the
              domain of the second y  axis and a y position of 0.5
              refers to the point between the bottom and the top of
              the domain of the second y axis.
