(JavaScript) Add Image to HTML Email
Demonstrates how to add an image to an HTML email.
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var email = new CkEmail();
email.From = "Matt <matt@example.com>";
email.AddTo("Joe","joe@example.com");
email.Subject = "This is a test";
// Add an HTML body with an image tag.
var html = "<html><body><p>Test with image:</p><p><img src=\"/wildlife/starfish.jpg\" /></p></body></html>";
email.SetHtmlBody(html);
// Add the image data from a file. The pathInHtml must match the value of the img tag's src attribute.
var pathInHtml = "/wildlife/starfish.jpg";
// The actual path of the JPG file in the local filesystem:
var pathOnDisk = "qa_data/jpg/starfish20.jpg";
success = email.AddRelatedFile2(pathOnDisk,pathInHtml);
if (success == false) {
console.log(email.LastErrorText);
return;
}
// The email is now properly constructed with an image that will be visible in the HTML.
// In this example, we'll save it to a .eml file and verify by loading the .eml in an email client such as Mozilla Thunderbird.
success = email.SaveEml("qa_output/starfish.eml");
// Also, we can examine the MIME to understand how the image data in the MIME is associated with the img tag in the HTML.
// It is the Content-Location header value that must match the value of the img tag's src attribute.
console.log(email.GetMime());
// Here's the MIME:
// MIME-Version: 1.0
// Date: Thu, 26 May 2022 11:09:12 -0500
