Here's what I tried, using your example

\define linkimage(title,url)
<$link to="$title$"><img 
src="$http:\\orbit/livelink/llisapi.dll/open/5270759$"></$link>
\end

Here is an image: <<linkimage MyTiddler myimage.jpeg>>

Nothing displayed - I should have seen the JPG image which the URL 
referenced.  Am I missing something obvious?
