Beyond that, why not keep it conforming to HTML, and use an <IMG> tag,
for example:
This is some text <img src="name.jpg" alt="Alt Text" processat="server">.
That way if you need to view the page "as-is" in a browser or whatever,
it'd still look fine.. go grab yourself some good free html parser code,
and analyse the options. If processat="server" then do your thing, and
re-write the <img> tag. :)
