In Paris release.....there is a new type of PNG that allows users to see the bar or pie chart images

If the report output type is Embedded PNG,

• Use the tag ${report:png} in the message body to position the report at a specific place in the message. Otherwise, the report is placed at the bottom of the message.
• Use the tag ${report:include_with} to position other reports included with the email. Otherwise, these reports are placed at the bottom of the message.
