I try to send a HTML newsletter to myself and find that all the images file cannot display. I viewed the source code and find that all the src="a.jpg" are gone but remain <img alt="a.jpg" border="0" height="100" width="300">.

 

I would like to know how to solve it?

I am using dnn 4.3.5

Thank you

If you have a look at the HTML code for your newsletter, you may find that your text editor is creating relative links for your images ie: "/portals/0/myimage.gif"

But in order for the email to work, you need to work with the full URL ie:
"http://www.mywebsite.com/portals/0/myimage.gif"

The default text editor should work correctly as it creates the full URL, if you are using the FCKEditor, you need to apply a setting:

For the FCKEditor
When in the newsletter module, click on Show custom editor options
Other Editor options
Tick Full Image Path
Apply Custom Settings to "This Module" click on Apply
close the FCKEditor options window

- On a side note I have just been testing the newsletter module with the default text editor in v 4.4 and it seems buggy when adding images, so if you are having problems, I would recommend using the FCKEditor as it works without problems.
