Creating an Email Message

To create an email message using Aspose.Email, you’ll need to import the necessary libraries and initialize the MailMessage object. Here’s a code snippet to get you started:

// Import necessary libraries
import com.aspose.email.*;

// Create a new email message
MailMessage message = new MailMessage();

Adding Image as Attachment

To attach an image to your email, you’ll need to specify the image file’s path and add it as an attachment. Here’s how you can do it:

// Specify the path to the image file
String imagePath = "path/to/your/image.jpg";

// Attach the image to the email
Attachment attachment = new Attachment(imagePath);
message.getAttachments().add(attachment);

Embedding the Attached Image

To embed the attached image within the email body, you can use the LinkedResource class. This allows you to reference the attachment within the email’s HTML body:

// Create a LinkedResource for the attached image
LinkedResource linkedImage = new LinkedResource(attachment.getContentStream(), "image/jpeg");
linkedImage.setContentId("image1");

// Create an HTML body with the embedded image
String htmlBody = "<html><body><h1>Check out this image:</h1><img src='cid:image1'></body></html>";
message.setHtmlBody(htmlBody);
message.getLinkedResources().addItem(linkedImage);

Sending the Email

Now that you have created an email message with the embedded image, you can send it using Aspose.Email’s SmtpClient:

// Initialize the SmtpClient
SmtpClient client = new SmtpClient("smtp.example.com", 587, "your_username", "your_password");

// Send the email
client.send(message);

Congratulations! You’ve successfully embedded an image as an attachment in an email using Aspose.Email for Java. Your emails will now be more visually engaging and informative.
