I'm working to create an HTML email which includes 2 images. Currently, I'm using tags to place the image in the email. Problem is when users get the email, it's asking the user to "click to download" for security reasons.
Is there a way to embed the image in the email, to avoid this issue?
I'm using Coldfusion to send the email.
Thanks
I haven't tested if this works in e-mail clients, but if you encode the image as Base64 you can include it in the HTML, which avoids the issue of connecting to a remote server.
Here's how you can do this with CFML:
<cfset ImageFile = "/path/to/image.png" />
<cfset ImageInfo = "image/png;charset=utf-8;base64" />
<cfset ImageData = ToBase64( FileReadBinary( ImageFile ) , 'utf-8' ) />
<cfoutput>
<img src="data:#ImageInfo#,#ImageData#" alt="my picture" />
</cfoutput>
You can embed the image as an attachment using cfmailparam and link to the attachement instead of an external file.

I am fairly certain that is an email client issue and not the email/HTML you are putting together. I am unaware (and a quick Google didn't show) of any ways to get around this with HTML.
One possible solution may be to create a rich text email instead and embed the image in the RTF, not sure if that will get you around your issue or not.
Other thought is do you have to have the images in the email? You might be better of crafting the email format to not rely on the images for formatting/aesthetics but allow them to be included if the client displays them. Not sure who your target audience is but in my job we have to deal with users that are restricted to plain text email quite often.
