-## Tooltip image
-
-To display an image in a tooltip you can use the [Vega Tooltip plugin](#plugin). Vega Tooltip requires the special field name `image` to indicate that the field values should be rendered as images instead of displayed as text. The image tooltip can be specified either by setting the `tooltip` property of the mark definition (as detailed above) or by passing the field _as an array_ to the tooltip encoding channel, as in the example below:
-
-<div class="vl-example" data-name="text_tooltip_image"></div>
-
-In addition to providing the path to an image, the Vega Tooltip plugin can also render base64 encoded images prefixed with `data:image/png;base64,` [similarly to how these are rendered inside HTML image tags](https://www.w3docs.com/snippets/html/how-to-display-base64-images-in-html.html). To change the maximum size of the rendered tooltip images, you can adjust the `max-width` and `max-height` properties of the CSS selector `#vg-tooltip-element img`.
-
 ## Disable tooltips
 
 To disable tooltips for a particular single view specification, you can set the `"tooltip"` property of a mark definition block to `null`.
