RTF does not satisfy most of the requirements to the CodeProject articles actually implemented in CodeProject CSS styles, scripts, etc., and actually used in most articles. HTML is the standard for Web, not RTF. And I simply don't know a single RTF feature not available in HTML. Formatting? RTF ad-hoc formatting style can not satisfy event the basic requirements, because styles are really needed for a good article.
Please read CodeProject formatting guidelines:
Pay attention that the editors are supposed to remove extraneous formatting.
As to your question on the images embedded in the article, you can do it simply by using
<img alt="your text" src="relative image URL" />
in raw HTML mode. I would suggest you load any available article, click "View" / "Page Source" to see how it is done.
The HTML editor provided with the submission wizard provides the image tool, please see the menu items under the text area.
If you still have particular questions on submission of your article, ask them via e-mail Submit@codeproject.com
. If you have general suggestions or a bug report, submit it here: http://www.codeproject.com/Forums/1645/Site-Bugs-Suggestions.aspx
