Sending a chart in mail body - vba

Question

I'm trying to modify Ron de Bruin's code to send a chart in mail body.
I export the chart and save it as an PNG image, then I modify HTML code to add it to the message.
The code should run on a server and send mails to people in my workplace.
When using MailItem.Display and manually clicking "send" when my message appears, everything works.
When I try to use MailItem.Send I get an icon in the mail body like it tried to attach an image which it couldn't find.
When I send that mail from a server, on a server account, the chart is displayed correctly.
It doesn't work when I try to send it on "local" computers.

I tried to use the Wait function directly after the Send method.

Getting the images to appear as inline is certainly possible. The img src in the HTML must refer to the cid with an identifier for the image. The code below sets up the email and adds all of the chart objects as inline images to an email.
Option Explicit
Sub CreateEmail()
Const PR_ATTACH_MIME_TAG = "http://schemas.microsoft.com/mapi/proptag/0x370E001E"
Const PR_ATTACH_CONTENT_ID = "http://schemas.microsoft.com/mapi/proptag/0x3712001E"

'--- create the email body with HTML-formatted content
msgGreeting = "<bold>Dear Sirs</bold>,<br><br>"
msgPara1 = "<div>Here is the data you requested:</div>"

'--- build the other email body content
Set wb = ActiveWorkbook

For Each chrt In ws.ChartObjects

tempFiles.Add fname

Excellent! I couldn't manage to attach the active workbook into the mail.
I tried to add the code .Attachments.Add (ActiveWorkbook.FullName) but didn't work, I received a message saying that the file is in use, and sometimes Runtime error 424 - Object required
With olMail
.To = "yyy#zzzz.com"
'.CC = "xxxx#xxx"
.Subject = "xxxx"
.Attachments.Add (ActiveWorkbook.FullName) ' this i added
