Delphi Example

To attach an inline images to email, you should add an attachment to email at first. Then you should assign an unique identifier(contentid) to this attachment. Finally, you need to replace the <img src="your file name" /> to <img src="cid:yourcontentid" />.

The following example codes demonstrate how to send HTML email with inline images.

Code:

// To run it correctly, please change SMTP server, user, password, sender, recipient value to yours

Unit Unit1; 

Interface 

Uses 
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, 
  Dialogs, StdCtrls, EASendMailObjLib_TLB; // add EASendMail Unit 

Type 
  TForm1 = Class(TForm) 
    Button1: TButton; 
    Procedure Button1Click(Sender: TObject); 
  private 
    { Private declarations } 
  public 
    { Public declarations } 
  End; 

Var 
  Form1: TForm1; 

Implementation 

{$R *.dfm} 

Procedure TForm1.Button1Click(Sender: TObject); 
Var 
  oSmtp : TMail; 
  cid : WideString; 
Begin 
  oSmtp := TMail.Create(Application); 
  oSmtp.LicenseCode := 'TryIt'; 

  // Set your sender email address
  oSmtp.FromAddr := 'test@emailarchitect.net'; 

  // Add recipient email address
  oSmtp.AddRecipientEx( 'support@emailarchitect.net', 0); 

  // Set email subject
  oSmtp.Subject := 'test HTML email from Delphi with embedded images'; 

  // Add embedded image and return the unique identifier of the attachment
  cid := oSmtp.AddInline('c:\test.jpg' ); 
  If cid = '' Then 
  Begin 
  ShowMessage( 'Failed to add embedded image with error: ' + 
      oSmtp.GetLastErrDescription()); 
      exit; 
  End; 

  // Set HTML body format
  oSmtp.BodyFormat := 1; 

  // Set HTML body
  oSmtp.BodyText := '<html><body>Hello, this is an embedded <img src="cid:' + 
  cid + '"> picture.</body></html>'; 

  // Your SMTP server address
  oSmtp.ServerAddr := 'smtp.emailarchitect.net'; 

  // User and password for ESMTP authentication, if your server doesn't require
  // user authentication, please remove the following codes
  oSmtp.UserName := 'test@emailarchitect.net'; 
  oSmtp.Password := 'testpassword'; 

  // If your SMTP server requires SSL connection, please add this line
  // oSmtp.SSL_init();

  ShowMessage( 'start to send email ...' ); 

  If oSmtp.SendMail() = 0 Then 
    ShowMessage( 'email was sent successfully!' ) 
  Else 
    ShowMessage( 'failed to send email with the following error: ' 
    + oSmtp.GetLastErrDescription()); 

End; 

End.
