I want to send html-newsletters with images. Doing this per
<img src="url"..doesn't work at all clients. Mac-Mail for example doesn't show the images, it even doesn't show anything, where the image should be.
Doing some googleing, I learned, that I should send the image as attachment, define an id and show it per
<img src="cid:theID... />
Does anybody know, how to realise this with the post-notification plugin? I don't know where to start, but as far, as I understand my problem, there are two topics to solve.
- how to add an attached file to the newsletter
- if 1 works, what is the cid I have to use
