Hello

I have partly followed this tutorial:

Sending email with an embedded image through ASP.NET[^]

and, though the user receives his email, when I test my SMTP locally, the plain background image (600px x 600px) does not appear. In Visual Studio (2013), I don't get any errors. The image, emailBG.jpg, is in my Images folder in Solution Explorer, and the code I am using to send plain and HTML emails, and for the background image, is as follows:

HTML

Dim PlainMessage As AlternateView = AlternateView.CreateAlternateViewFromString("Hello. To reset your password....Nothing, "text/plain")
Dim mimeType As ContentType = New ContentType("text/html")
Dim HtmlMessage As AlternateView = AlternateView.CreateAlternateViewFromString("<p style......Nothing, "text/html")
Dim Logo As New LinkedResource(Server.MapPath("~/Images/emailBG.jpg"), "image/jpeg") 'embedded image
Logo.ContentId = "emailBG"

myMessage.AlternateViews.Add(PlainMessage)
myMessage.AlternateViews.Add(HtmlMessage)</<pre lang="HTML">

pre>

Thanks for any advice.

Hello Richard

Thanks for your reply.

The article is 10 years old - not sure if the author will even see it.

Thanks again.

Looks like the HTML version of your message has been truncated, so we can't see what styles you've applied.

And remember, if you're setting a background image for a <p> tag, it will be cropped to the site of that paragraph of text. You probably want to specify the <body> tag, and put the background image there:

Dim HtmlMessage As AlternateView = AlternateView.CreateAlternateViewFromString("<body style=""background:url('cid:emailBG') no-repeat;"">...</body>", Nothing, "text/html")

Yes, you're right. I do have that against 'p' at the moment:

("<p style='font-family, etc.....'>Hello " & strEmailValue & "<br /><br /> To reset your password....etc</p>", Nothing, "text/html")

I will take on board what you suggest about 'body' as opposed to 'p' and use your 'cid:email.BG'.

Would I still need these two lines that follow the above line I have posted above:

Dim Logo As New LinkedResource(Server.MapPath("~/Images/emailBG.jpg"), "image/jpeg") 'embedded image
 Logo.ContentId = "emailBG"

Isn't 'Logo.ContentId = "emailBG"' a repetition of your 'cid:emailBG'?

Thanks.

Can you see this message though it is not in 'Preview'?

Richard Deeming26-Feb-17 6:10

Yes, you'd still need the linked resource.

The cid: is the protocol which lets the mail client know that the image should be loaded from the linked resources in the message, rather than trying to load it from a file or a website.

So cid:emailBG in the HTML is a URL that points to the embedded resource with the content ID set to emailBG.

How do I embed images in an email?[^]

Hi,

I have developed audio recording facility to my website.. But it is giving wav formatted base64string.. Can we convert wav to mp3 format or if possible can we reduce base64String size? Because internet explorer is supporting only mp3 files to play.. Is there any way to solve my issue?

Any suggestion will be useful for me.. Thanks in advance..

We need to see the context. Where is this code being called from?
