Problem with copying charts into html body outlook

Hello

I am attempting to copy one active sheet into html body outlook message.

I have the following code, which is adding the attachments however my charts still do not appear.

I am attempting to add one chart for now, but once complete will need to add all 5 from the page.

Any help with the code would be much, much appreciated.

Thank you
