Hi Celadon.
A couple of things ...
1. The format for embedding an image is:
<img src="http://www.crosswordsolver.org/images/logo.png" alt="CCS logo" />
2. You seem to be trying to link a document from within a Google Docs account. As not everyone will have a Google Docs account (or, even if they do, will not be signed on to it), I think that your image link may not work as you intended.
