The rendered HTMl will also be added as a flow variable "html-content" which can be accessed using the flow variable port.
For use in emails PNG Cells can now also be selected for addition to the HTML table. In the cell containing an image an image tag will be created with 'cid:image-{row-index}' as the identifier for the image. For the image to render then the images column must have it's values added to the email as embedded attachments using the same naming scheme of image-{array-index} as the Content-ID value. The images will not render within the KNIME table preview. More information may be seen here.
