Embedding an image into an HTML email

[Alc]

I've found this question asked a few times on the forum, but in almost all cases it was never answered and in the others I can't follow the explanation given

This is the code I currently use to automatically generate emails and it works just fine.

Sub Email_IA()
    Dim NameSpace As Object
    Dim EmailSend As MailItem
    Dim EmailApp As Object
    Dim str_Source_Path As String
    Dim str_Subject As String
    Dim str_Body As String
    Dim str_To As String
    Dim str_From As String
    
    str_Subject = "Test Subject"
    str_Body = DLookup("Body", "tbl_Email_Bodies", "Email_Type = 112")
    str_To = IIf(IsNull([Forms]![frm_referral_from]![Received from Email]), "", [Forms]![frm_referral_from]![Received from Email])

    Set EmailApp = CreateObject("Outlook.Application")
    Set objeoutlookmsg = EmailApp.GetNamespace("MAPI")
    Set EmailSend = EmailApp.CreateItem(0)
    
    EmailSend.BodyFormat = olFormatHTML
    EmailSend.To = str_To
    EmailSend.Subject = str_Subject
    EmailSend.HTMLBody = str_Body
    
    EmailSend.Save
    EmailSend.Display
End Sub

What i would like to is to embed an image, based on a filepath stored as part of the value set for str_Body. I've tried setting str_Body to the following.

<p>Test body</p><img src="G:\Project Folder\Back Office Information.JPG"><p>End of test body</p>

This works fine within the local team, as everyone has access to the folder in which the JPG is stored. Sending the same mail outside the department doesn't work, dut to the recipient not having access to the same folder.

Does anyone know an easy way to amend the above - either the HTML part or the VBA itself - such that I can send an image which anyone can read.

In case it makes a difference, all recipients will be using Outlook for their email.

Thanks in advance.
