I have some images stored in the Resources.resx file in my solution. I would like to use these images in my email. I have loaded the image into a variable:
Bitmap myImage = new Bitmap(Resources.Image);
and now I want to put it in the HTML in the AlternateView string I am using to create the HTML email. Just need some help.
Here is the HTML string(partial):
body += "</HEAD><BODY><DIV style='height:100%; width:700px;'><div style='height:70px; width:700px; background-color:red;'><img src='" + myImage + "' width='104' height='27' alt='img' style='margin: 20px 0px 0px 20px;'/></div>
Any help would be greatly appreciated Thanks!
EDIT: Here is the entire Code block. I think I am close to getting it, just inexperience getting in the way here :) I tried converting it into a Byte like suggested which got me farther. Still not rendering the image. There is something here I am not doing right. Thank you so much for all of you help everyone! Here is the code (the HTML I need for the image is in the 3 line of the string body = code):
if (emailTo != null)
{
Bitmap myImage = new Bitmap(Resources.comcastHeader);
ImageConverter ic = new ImageConverter();
Byte[] ba = (Byte[])ic.ConvertTo(myImage, typeof(Byte[]));
MemoryStream image1 = new MemoryStream(ba);
LinkedResource headerImage = new LinkedResource(image1, "image/jpeg");
headerImage.ContentId = "companyLogo";
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("" + emailTo + "");
message.Subject = "" + customer + " Your order is being processed...";
message.From = new System.Net.Mail.MailAddress("[email protected]");
string body = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">";
body += "<HTML><HEAD><META http-equiv=Content-Type content=\"text/html; charset=iso-8859-1\">";
body += "</HEAD><BODY><DIV style='height:100%; width:700px;'><div style='height:70px; width:700px; background-color:red;'><img src=\"cid:companyLogo\" width='104' height='27' alt='img' style='margin: 20px 0px 0px 20px;'/></div><P>Hello " + customer + ",</P><P>Thank you for shopping at <a href='" + store + "'>" + store + "</A>.

Position your cursor where you want the image in your message. Select Insert > Pictures. Browse your computer or online file locations for the picture you want to insert. Select the picture, then select Insert.
Embedding an image into an email message is the act of adding the image into the coding of the email template for it to appear amongst the text once the subscriber opens it, instead of appearing as an email attachment.
To attach an image, you need to have the encoding scheme of the image you want to attach. This is the base64 string of the picture. You can get this by right-clicking on the image you want to attach, copy the image address, and paste it into the HTML text. The recipient will have a preview of when they open the email.
you need to add them in the email message as CID's/linked resources.
here is some code I have used before which works nicely. I hope this gives you some guidance:
Create an AlternateView:
AlternateView av = AlternateView.CreateAlternateViewFromString(body, null, isHTML ? System.Net.Mime.MediaTypeNames.Text.Html : System.Net.Mime.MediaTypeNames.Text.Plain)
Create a Linked Resource:
LinkedResource logo = new LinkedResource("SomeRandomValue", System.Net.Mime.MediaTypeNames.Image.Jpeg);
logo.ContentId = currentLinkedResource.Key;
logo.ContentType = new System.Net.Mime.ContentType("image/jpg");
// add it to the alternative view
av.LinkedResources.Add(logo);
// finally, add the alternative view to the message:
msg.AlternateView.Add(av);
here is some documentation to help you with what the AlternativeView and LinkedResources are and how it works:
http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.alternateviews(v=vs.110).aspx http://msdn.microsoft.com/en-us/library/system.net.mail.linkedresource(v=vs.110).aspx http://msdn.microsoft.com/en-us/library/ms144669(v=vs.110).aspx
in the HTML itself, you need to do something like the following:
"<img style=\"width: 157px; height: 60px;\" alt=\"blah blah\" title=\"my title here\" src=\"cid:{0}\" />";
notice the CID followed by a string format {0} - I then use this to replace it with a random value.
UPDATE
To go back and comment on the posters comments... here is the working solution for the poster:
string body = "blah blah blah... body goes here with the image tag: <img src=\"cid:companyLogo\" width="104" height="27" />";
byte[] reader = File.ReadAllBytes("E:\\TestImage.jpg");
MemoryStream image1 = new MemoryStream(reader);
AlternateView av = AlternateView.CreateAlternateViewFromString(body, null, System.Net.Mime.MediaTypeNames.Text.Html);
LinkedResource headerImage = new LinkedResource(image1, System.Net.Mime.MediaTypeNames.Image.Jpeg);
headerImage.ContentId = "companyLogo";
headerImage.ContentType = new ContentType("image/jpg");
av.LinkedResources.Add(headerImage);
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.AlternateViews.Add(av);
message.To.Add(emailTo);
message.Subject = " Your order is being processed...";
message.From = new System.Net.Mail.MailAddress("[email protected]");
ContentType mimeType = new System.Net.Mime.ContentType("text/html");
AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType);
message.AlternateViews.Add(alternate);
// then send message!

One option is put the image in one host, and in the src put the url, like this "src='http://www.host/myImage.jpg'" This way you do not have to load the image in each mail and would be more agile.

If it helps anyone, here is a version based on Ahmed ilyas' very useful answer, which passes the actual Bitmap to the memory stream, and encloses the various objects which implement IDisposable in using blocks -
public void SendMailExample(string emailAddressTo, string hexColour)
{
// Give the LinkedResource an ID which should be passed into the 'cid' of the <img> tag -
var linkedResourceId = "mylogo";
var sb = new StringBuilder("");
sb.Append("<body><p>This is the HTML email body with img tag...<br /><br />");
sb.Append($"<img src=\"cid:{linkedResourceId}\" width=\"100\" height=\"115.5\" alt=\"Logo\"/>");
sb.Append("<p></body>");
var emailBodyHtml = sb.ToString();
var emailBodyPlain = "This is the plain text email body";
using (var message = new MailMessage())
using (var logoMemStream = new MemoryStream())
using (var altViewHtml = AlternateView.CreateAlternateViewFromString(emailBodyHtml, null, System.Net.Mime.MediaTypeNames.Text.Html))
using (var altViewPlainText = AlternateView.CreateAlternateViewFromString(emailBodyPlain, null, System.Net.Mime.MediaTypeNames.Text.Plain))
using (var client = new System.Net.Mail.SmtpClient(_smtpServer)
{
Port = 25,
DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
EnableSsl = false
})
{
message.To.Add(emailAddressTo);
message.From = new MailAddress(_emailAddressFrom);
message.Subject = "This is the email subject";
// Assume that GetLogo() just returns a Bitmap (for my particular problem I had to return a logo in a specified colour, hence the hexColour parameter!)
Bitmap logoBitmap = GetLogo(hexColour);
logoBitmap.Save(logoMemStream, System.Drawing.Imaging.ImageFormat.Png);
logoMemStream.Position = 0;
using (LinkedResource logoLinkedResource = new LinkedResource(logoMemStream))
{
logoLinkedResource.ContentId = linkedResourceId;
logoLinkedResource.ContentType = new ContentType("image/png");
altViewHtml.LinkedResources.Add(logoLinkedResource);
message.AlternateViews.Add(altViewHtml);
message.AlternateViews.Add(altViewPlainText);
client.Send(message);
}
}
}
