Excel VBA Embed Individual Images to List of Email Contacts - vba

Question

I have been assigned to send out Christmas greetings that have been customized to specific customers. However, these greetings are in the 100's and doing it automatically would save me hours - and these greetings are done every year!
In Excel, the customer names are listed in column A, the individual emails in column B, and the path to the individual customized greeting file in column C.
What I have currently found is a VBA code that offers me the option to attach (but not embed) these files through their paths to the individual emails.
Might anyone explain to me and/or demonstrate how to embed the attached files that are found through column C ?
Thank you very much!
What I have now is the following:
Sub Send_Files()
'Working in Excel 2000-2016
'For Tips see: http://www.rondebruin.nl/win/winmail/Outlook/tips.htm
Dim OutApp As Object
Dim OutMail As Object
Dim sh As Worksheet
Dim cell As Range
Dim FileCell As Range
Dim rng As Range
With Application
.EnableEvents = False
.ScreenUpdating = False
End With
Set sh = Sheets("Sheet1")
Set OutApp = CreateObject("Outlook.Application")
For Each cell In sh.Columns("B").Cells.SpecialCells(xlCellTypeConstants)
'Enter the path/file names in the C:Z column in each row
Set rng = sh.Cells(cell.Row, 1).Range("C1:Z1")
If cell.Value Like "?*#?*.?*" And _
Application.WorksheetFunction.CountA(rng) > 0 Then
Set OutMail = OutApp.CreateItem(0)
With OutMail
.to = cell.Value
.Subject = "Merry Christmas!"
.Body = "Merry Christmas!"
For Each FileCell In rng.SpecialCells(xlCellTypeConstants)
If Trim(FileCell) <> "" Then
If Dir(FileCell.Value) <> "" Then
.Attachments.Add FileCell.Value, olByValue, 0
End If
End If
Next FileCell
.Send 'Or use .Display
End With
Set OutMail = Nothing
End If
Next cell
Set OutApp = Nothing
With Application
.EnableEvents = True
.ScreenUpdating = True
End With
End Sub

You could do using HTML email, something like
Set o = Application.CreateItem(olMailItem)
o.BodyFormat = olFormatHTML
o.HTMLBody = "<img src='C:\Users\Pictures\a1.png'>"
o.Display
