this triggers the exception var imageEmbedder = (ImageEmbedder)html.ViewData["Postal.ImageEmbedder"];

I seem to be getting this too. Is there any way to get this fixed or a work around we could employ to get this to work?

I also have experienced the same issue. I am wondering if I am missing some dependency. It is a little bit of a pain as this plugin is so easy to use else-wise.

The workaround is to only use "Embed Images" using multi-part emails (ie, one that has both plain-text and html views). Obviously, you only put the image in the HTML view. :) The example supplied in the documentation does not work.

Thank you Pharylon for your prompt response. I very much appreciate the heads up so we can continue with our application development knowing how to move forward effectively.

I have tested pharylon's response and it is correct. You must create a text and html version of the email if you would like to use embed images. A bit frustrating seeing as this isn't specified anywhere. I only needed to create html version as this was used in an internal application. And to find out I needed to create dummy text versions just to get this to work was bewildering.

Thus, for any future users who might come across this issue, follow this guide http://aboutcode.net/postal/multi-part.html and then the images should work.
